	Update ThreadLocal to use default(T) for initialization with
	parameterless ctor following comment on
	https://connect.microsoft.com/VisualStudio/feedback/details/630350/threadlocal-documentation-and-actual-behavior-mismatch

2010-12-17  Jérémie Laval  <jeremie.laval@gmail.com>

	Backport ParallelFx changes from master in System.Threading

2010-12-13  Jérémie Laval  <jeremie.laval@gmail.com>

	Increment Count even on single-processor in SpinWait. Fix #624849.

2010-10-21  Gonzalo Paniagua Javier  <gonzalo.mono@gmail.com>

	Fix the collision handling code

	After the fix for bug #605092, inserting timers with an equal due
	time was failing because searching in the list was also using a
	reference comparison. Now, when adding a new timer, we search
	using just the due time. Fixes bug #648130.

2010-08-31  Jérémie Laval  <jeremie.laval@gmail.com>

	Fix non 4.0 build of ReaderWriterLockSlim.

	It needs to be cleaned up though.

2010-08-31  Jérémie Laval  <jeremie.laval@gmail.com>

	Factorize tatas pattern in TryRelaxedSet method in AtomicBoolean,
	add AtomicBoolean to the compilation file list for System.Core

2010-08-26  Jérémie Laval  <jeremie.laval@gmail.com>

	Rework ReaderWriterLockSlim to use simpler Interlocked arithmetic.

2010-08-19  Jérémie Laval  <jeremie.laval@gmail.com>

	Remove timed deep sleep in ManualResetEventSlim and instead
	combine several WaitHandle to wait on

2010-08-13  Jérémie Laval  <jeremie.laval@gmail.com>

	Move NET_4_0 define checks at the right position under the licence
	text

2010-08-13  Jérémie Laval  <jeremie.laval@gmail.com>

	Add BOOTSTRAP_NET_4_0 define check in LazyInitializer (since it's
	now used in ManualResetEventSlim).

2010-08-13  Jérémie Laval  <jeremie.laval@gmail.com>

	Port CountdownEvent to use a ManualResetEventSlim for all its
	waiting operations and use it as the native handle too.

2010-08-13  Jérémie Laval  <jeremie.laval@gmail.com>

	Lazy initialization of ManualResetEventSlim's underlying kernel
	object.

	It avoids allocating kernel ressources when the standard fast path
	is used which is the main goal of this type.

2010-08-11  Gonzalo Paniagua Javier  <gonzalo.mono@gmail.com>

	Adapt to new exception in threadpool behavior.

	Since an exception in the threadpool can kill the application,
	silently ignore it when we know it is not harmful.

2010-08-09  Jb Evain  <jbevain@gmail.com>

	Fix typo

2010-08-04  Jérémie Laval  <jeremie.laval@gmail.com>

	Include set accessor in ThreadLocal's Value property. Catch
	possible exception in the initialization function and re-throw it
	accordingly. Track circular calling of Value property. Add
	corresponding unit-tests.

2010-08-04  Jérémie Laval  <jeremie.laval@gmail.com>

	Add missing BOOTSTRAP_NET_4_0 define check in ManualResetEventSlim
	(as BlockingCollection now depends on that type).

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Use SemaphoreSlim underlying kernel-based event to sleep deeper
	when too much time has already been spent spinning.

	Same rationale change than ealier ManualResetEventSlim commit.

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Correctly uses CancellationToken's ThrowIfCancellationRequested
	method in SemaphoreSlim and throw OperationCanceledException
	instead of returning false.

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Correctly set SemaphoreSlim underlying kernel-based event state
	when it's changing state itself.

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Correctly use ManualResetEventSlim's kernel-based counterpart to
	deep sleep when too much has already been spent spinning.

	Instead of using solely SpinWait's SpinOnce method after
	ManualResetEventSlim's spinCount is reached, it now uses
	ManualResetEvent's WaitOne method. Various other checks like
	CancellationToken canceled state are still verified during that
	time albeit slower.

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Use directly CancellationToken's ThrowIfCancellationRequested in
	ManualResetEventSlim

2010-08-03  Jérémie Laval  <jeremie.laval@gmail.com>

	Revert stalling changes introduced in SpinWait. Add a guard for
	ntime overflow.

	The deeper-sleep stalling code path is now delegated to the
	concerned types rather than being directly inside SpinWait.

2010-07-31  Jérémie Laval  <jeremie.laval@gmail.com>

	[Fix] Adjust SpinWait values to stall the thread earlier. Fix
	#624849.

2010-05-17 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Timer.cs: check object reference when the timers are equal.
	Fixes bug #605092.

2010-04-23  Rolf Bjarne Kvinge  <RKvinge@novell.com>

2010-03-23  Sebastien Pouliot  <sebastien@ximian.com>

	* Monitor.cs: Implement new NET_4_0 (and SL4) Enter overload 
	required to run some DRT tests (e.g. 7007)

2010-03-16  Jb Evain  <jbevain@novell.com>

	* ThreadPool.cs, Thread.cs, ExecutionContext.cs: use MOONLIGHT
	symbol to disambiguate MonoTouch and Moonlight code.

2010-03-08  Jérémie Laval  <jeremie.laval@gmail.com>

	* SpinLock.cs: Merge algorithm back in SpinLock struct

	* ThreadLocal.cs: Port to .NET 4 beta 2 API

2009-12-09  Jb Evain  <jbevain@novell.com>

	* ThreadPool.cs (QueueUserWorkItem): properly throw
	an ANE instead of triggering a NRE when being passed a null callback.

2009-11-02  Miguel de Icaza  <miguel@novell.com>

	* Jumbo patch to drop support for pre-NET_2_0 code:

	Remove ONLY_1_1 code
	Remove NET_1_0 only code
	Remove NET_2_0 defines assuming the value is true.

2009-11-02  Sebastien Pouliot  <sebastien@ximian.com>

	* Thread.cs (set_CurrentUICulture): Delay setting in_currentculture
	to true until after the null check and the return statement.

2009-11-02  Jérémie Laval  <jeremie.laval@gmail.com>

	* Parallel.cs: Added fix for Bug #536919.

	* EventWaitHandle.cs: Add validation on the EventResetMode 
	parameter used in the constructors
	* Monitor.cs: Fix validations for TryEnter and Wait. Reduce 
	duplicated code between overloads.

2009-10-21  Sebastien Pouliot  <sebastien@ximian.com>

	* WaitHandle.cs: Add missing validations for 'millisecondsTimeout'
	in Wait[One|Any|All]. Also call the overloaded (bool) methods for
	WaitAll to reduce code duplication.

2009-10-20  Sebastien Pouliot  <sebastien@ximian.com>

	* Timer.cs: Always call Init from every constructors to avoid 
	duplicate checks. Fix validations on different dueTime and period
	(ctor and Change methods). Seal private TimerComparer class and
	avoid multiple (identical) casts in its Compare method. Seal 
	private Scheduler class.

2009-10-20 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Timer.cs: make sure we don't insert 2 timers with the same key.

2009-10-20  Jb Evain  <jbevain@novell.com>

	* Thread.cs: change type of the current_appcontext field to object
	to avoid triggering static constructors unless explicitely required.

2009-10-16 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Timer.cs: looks like any negative value is treated as Infinite.

	* Thread.cs: Serialize the principal so as not to make it cross
	appdomains.  Two new internal calls for copying byte arrays
	between domains.

2009-09-25  Mark Probst  <mark.probst@gmail.com>

	* Thread.cs: The Thread class is split up into Thread and
	InternalThread now.  We have exactly one InternalThread per
	thread, and at most one Thread per appdomain per thread.  Most
	data is stored in InternalThread.  All InternalThread objects live
	in the root domain.

	* Environment.cs: Corlib version bump.

2009-09-24 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Timer.cs: no need to wake up the scheduler when removing the next
	scheduled item.

2009-09-23 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Timer.cs: rewritten. It only has one queue now and it is sorted by
	due time. Before this changes, it was using a lot of CPU when there
	were a lot of 'future' timers.

	for NET_2_1

2009-09-22  Jb Evain  <jbevain@novell.com>

	* Timer.cs: MONOTOUCH doesn't support remoting, so do not pass
	true to exitContext when calling WaitOne on a WaitHandle.

	* SpinLock: Remove unused private methods.

2009-08-03  Zoltan Varga  <vargaz@gmail.com>

	* Thread.cs: Always call Thread_free_internal from the finalizer, since
	it frees other things besides the handle. Fixes #527576.

	Original patch from Alan McGovern

2009-06-10  Marek Safar  <marek.safar@gmail.com>

	* LockRecursionException.cs: New file.

2009-04-21  Mark Probst  <mark.probst@gmail.com>

	avoid it being shared between app domains.

2009-04-20  Rolf Bjarne Kvinge  <RKvinge@novell.com>

	* Thread.cs: For 2.1 ensure exceptions in threads are handled using the
	UnhandledException event mechanism in System.Windows.Application instead
	of crashing the application.

2009-04-18  Mark Probst  <mark.probst@gmail.com>

	* Thread.cs: Don't keep the current number formatter here because
	it's shared between app domains.

2009-04-18  Mark Probst  <mark.probst@gmail.com>

	* Thread.cs: Make the abort exception state a GC handle, to
	properly separate AppDomains.  Add internal method for getting the
	state object.

	* ThreadAbortException.cs: Get the abort exception state via the
	method in Thread.

2009-04-12 Gonzalo Paniagua Javier <gonzalo@novell.com>

2009-02-18  Jb Evain  <jbevain@novell.com>

	* SynchronizationContext.cs: add NET_2_1 SetThreadStaticContext
	method, even if already obsolete.

2009-01-30  Andreia Gaita  <avidigal@novell.com>

	* SynchronizationContext.cs: Remove moonlight hacks, dispatcher should
	be able to handle this now.

2008-12-20  Miguel de Icaza  <miguel@novell.com>

	* WaitHandle.cs: Add two overloads that were introduced in 3.5.

2008-11-25  Geoff Norton  <gnorton@novell.com>

	* SynchronizationContext.cs: A temporary horrible hack to SyncContext
	to hard-wire all calls back to the main thread (moonlight-only) so that
	we can use our unit test harness.  This will be fixed for 2.1 when we
	implement Dispatcher properly.

2008-10-30 Gonzalo Paniagua Javier <gonzalo@novell.com>

	* Interlocked.cs: make CompareExchange internal in 1.1 for use by the
	runtime.

2008-09-19  Miguel de Icaza  <miguel@novell.com>

	* WaitHandle.cs (WaitOne): Add new 3.5 SP1 overload.

	* Timer.cs: use a separate queue for timers that are far in the future
	so they don't need to be looked at as often (bug #418272).
	Better precision of recheduling time.

2008-07-03  Andreas Nahr  <ClassDevelopment@A-SoftTech.com>

	of key-value pairs.

2008-06-18  Kornél Pál  <kornelpal@gmail.com>

	because managed and native threads are currently bound together.

2008-06-14  Zoltan Varga  <vargaz@gmail.com>

	the "mono_thread_manage" callback.

Tue Feb 26 17:51:58 CET 2008 Paolo Molaro <lupus@ximian.com>

	* Timer.cs: use a monotonic clock to schedule timers
	(fixes part of bug#347476).

Fri Feb 22 11:23:53 CET 2008 Paolo Molaro <lupus@ximian.com>

	* Thread.cs: implemented Begin/EndCriticalRegion.

	* WaitHandle.cs: Ifdef out some unused code (found by Gendarme).

2008-01-06  Zoltan Varga  <vargaz@gmail.com>

	(set_CurrentUICulture): Ditto.

2008-01-03  Zoltan Varga  <vargaz@gmail.com>

	* Thread.cs (set_CurrentCulture): Avoid the serialization overhead if
	the new culture is equal to the old one.

2007-12-27  Zoltan Varga  <vargaz@gmail.com>

	* Thread.cs: Change the type of synch_cs to an IntPtr to be in synch with the

	* ReaderWriterLock.cs : ... and avoid extra finalizer call.

2007-11-20  Atsushi Enomoto  <atsushi@ximian.com>

	* ReaderWriterLock.cs : adding missing 2.0 destructor (does nothing).

Thu Nov 8 18:36:25 CET 2007 Paolo Molaro <lupus@ximian.com>

	* Timer.cs: if period is 0 with a non-infinite due time, we
	run the callback just once (bug #340212).

2007-10-24  Dick Porter  <dick@ximian.com>

	* Thread.cs: Call Thread_init on the new 2.0 constructors too.

2007-10-24  Dick Porter  <dick@ximian.com>

	* Thread.cs: Assign the ManagedThreadId when it is asked for,
	rather than in the constructor, so ThreadPool threads also work.
	Fixes bug 335579 (and doesn't break 325367 or 325566)

2007-10-24  Atsushi Enomoto  <atsushi@ximian.com>

	* SynchronizationContext.cs : removed SendOrPost().

Wed Oct 17 13:24:33 CEST 2007 Paolo Molaro <lupus@ximian.com>

	* Timer.cs: better cleanup test for the expired array.

Tue Oct 16 17:22:15 CEST 2007 Paolo Molaro <lupus@ximian.com>

	* Timer.cs: remove expired timers from the the jobs list.

Tue Oct 16 12:14:43 CEST 2007 Paolo Molaro <lupus@ximian.com>

	* Timer.cs: rewrote to use threadpool threads to invoke the callbacks,
	avoid Thread.Abort and Thread.Interrupt and use a single scheduler
	thread, partially from the patch of Rafael Ferreira in bug #315999.
	Fixes bug #315999, #332206.

2007-10-15  Dick Porter  <dick@ximian.com>

	* Thread.cs: Initialise synch_cs to null now we aren't using it as
	a monitor lock

2007-09-25  Dick Porter  <dick@ximian.com>

	* Thread.cs: Keep ManagedThreadId constant over the lifetime of a
	Thread.  Patch from jlarimer@gmail.com fixing bugs 325367 and
	325566.

2007-09-25  Jonathan Pobst  <monkey@jpobst.com>

	* SynchronizationContext.cs: Implement SetSynchronizationContext.

2007-09-06  Dick Porter  <dick@ximian.com>

	* Timer.cs: Only hold a WeakReference to the runner thread, to
	work around an issue when finalizing at shutdown or (I think)
	appdomain unload.  (Basically, the Thread was being finalized
	first, but the Timer's finalizer was still trying to reference it
	subsequently.)

2007-08-10  Gert Driesen  <drieseng@users.sourceforge.net>

	* Thread.cs: Throw ThreadStateException when retrieving ApartmentState
	or IsBackground if thread is stopped. Fixes bug #81658.

2007-08-08  Zoltan Varga  <vargaz@gmail.com>

	* Thread.cs: Add a fixme.

2007-07-21  Miguel de Icaza  <miguel@novell.com>

	* WaitHandle.cs (Handle): It turns out that we should never create
	new SafeWaitHandles, as applications will assume that a
	SafeWaitHandle pulled from this will be the same after a Handle
	update (from Gert's test):

	
                AutoResetEvent are1 = new AutoResetEvent (false);
                AutoResetEvent are2 = new AutoResetEvent (false);
                SafeWaitHandle swh1 = are1.SafeWaitHandle;
                Console.WriteLine ("#A1:" + !swh1.IsClosed);
                Console.WriteLine ("#A2:" + !swh1.IsInvalid);
                IntPtr dummyHandle = (IntPtr) 2;

                Console.WriteLine ("#A8:" +
	        !are1.SafeWaitHandle.IsInvalid);

	We would return in A4, A5, A6 true, even when we have set the
	Handle ourselves.

	* WaitHandle.cs (Handle): in the 2.0 profile, explicitly dispose
	the old SafeWaitHandle, do not wait for the finalizer to run;

	Take ownership of the handle;   The docs did not say that
	assigning to this value would lead to a leak, the docs said that
	in the 1.0 and 1.1 profiles assigning to this property might lead
	to a leak.   My mistake. 

	Fixes: 82134

2005-05-09  Sebastien Pouliot  <sebastien@ximian.com> 

	* CompressedStack.cs: GetCompressedStack is public before 2.0 but

	* ReaderWriterLock.cs: When a thread holds a writer lock, a call to
	  AcquireReaderLock works like a call to AcquireWriterLock.

2004-04-06  Lluis Sanchez Gual <lluis@ximian.com>

	* Monitor.cs: In Wait(), release the synchronization context when 
	  exitContext is true.

2004-04-06  Lluis Sanchez Gual <lluis@ximian.com>

	* LockCookie.cs: Keep in this class the count of reader or writer locks
	  for a thread, not only whether it has locks or not.
	* LockQueue.cs: Added property for checking if a thread is waiting in
	  the queue. Wait now returns a boolean that set to false on timeout 
	  expiration.
	* ReaderWriterLock.cs: Started fixing bugs but I had to rewrite a lot of it.
	  The main change is that now it keeps a reader lock count for each
	  thread. This is needed since methods like ReleaseLock or 
	  UpgradeToWriterLock need to return a per-thread status in LockCookie.
	  Also added support for recursive writer-lock requests.

2004-03-21  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* ThreadAbortException.cs: use same HResult as MS.

2004-03-15  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* NativeOverlapped.cs: added 2 new internal fields.
	* Overlapped.cs: implemented, but it's not used.

	* Thread.cs: Implemented CurrentPrincipal.

2004-01-22  Gonzalo Paniagua Javier <gonzalo@ximian.com>

2003-10-01  Zoltan Varga  <vargaz@freemail.hu>

	* Thread.cs: Add locking to AllocateNamedDataSlot and 
	FreeNamedDataSlot.

Wed Aug 20 12:01:36 CEST 2003 Paolo Molaro <lupus@ximian.com>

	* Thread.cs: put all the fields at the start and add
	more fields needed by the runtime.

2003-08-14  Lluis Sanchez Gual  <lluis@ximian.com>

	* Thread.cs: SetData() method: use Hashtable.Contains to check
	  if a dataslot has been allocated (value could be null).

2003-07-23  Duncan Mak  <duncan@ximian.com>

	API, mark it as 'internal'.

2003-07-01  Dick Porter  <dick@ximian.com>

	* Thread.cs: Throw an exception if thread creation failed.
	(Better than just blowing up later.)

2003-06-27  Dietmar Maurer  <dietmar@ximian.com>

	* ThreadPool.cs: use async delegate invoke.

2003-06-25  Dick Porter  <dick@ximian.com>

	* WaitHandle.cs: Default handle value should be InvalidHandle, not
	Zero.

2003-06-21  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	milliseconds.

	* WaitHandle.cs: fixes for WaitAny/All and TimeSpan.

2003-06-06  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* WaitHandle.cs: checks and exceptions.

2003-06-02  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* NativeEventCalls.cs: added CloseEvent_intenal.
	* WaitHandle.cs: call CloseEvent_internal when disposing.

2003-05-31  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* RegisteredWaitHandle.cs: check that the callback is not null before
	invoking.

	* ThreadPool.cs: fixed timeout -> TimeSpan conversions (closes bug
	#43963). Queue the item before setting the handle. If there's a timeout,
	avoid trying to Dequeue, getting the exception et al, just continue the
	loop.

Mon May 19 09:07:45 CEST 2003 Paolo Molaro <lupus@ximian.com>

	* Monitor.cs: removed test_owner, the check is already done in the

2003-04-17  Pedro Mart?ez Juli? <yoros@wanadoo.es>

	* Timer.cs: Change the position of two lines because they were
	before the "if" that ensures the integrity. After this, the first of
	that two lines was producing a NullReferenceException.

2003-04-09  Dick Porter  <dick@ximian.com>

	* Thread.cs: Make sure a reference to the ThreadStart delegate is
	held.  There's no telling how long it will be before
	Thread.Start() is called, and GC might destroy the delegate.
	Thread() and Start() need to be rewritten so that the runtime
	creates the new thread when Start() is called, which will simplify
	the code a great deal.

2003-03-20  Miguel de Icaza  <miguel@ximian.com>

	* Thread.cs (CurrentCuluture): use the invaraint culture instead
	of "" for the current_culture setting.

2003-03-25  Zoltan Varga  <vargaz@freemail.hu>

	* Thread.cs: Fix visibility of ResetAbort().

	* Monitor.cs:
	* Thread.cs:
	* ThreadPool.cs:
	* Timer.cs:
	* WaitHandle.cs: Use TotalMilliseconds to convert a TimeSpan to
	ms, not Milliseconds.

2002-12-07  Martin Baulig  <martin@ximian.com>

	* Timer.cs: Make it actually work; now it no longer sets your
	application on fire if you use a zero periode and Timer.Change()
	actually works.

2002-11-11  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* Timer.cs: implemented more stuff. It works now.

2002-10-25  Zoltan Varga  <vargaz@freemail.hu>

	* Thread.cs: Implement GetDomain() and GetDomainID().

2002-10-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* ThreadPool.cs: now the monitor thread is not sleeping and checking if
	more worker threads needed. It waits on _DataInQueue. If (and only if)
	there's data in the queue it checks if more worker threads needed and
	then sleeps 0.5s before waiting for queued data again.

2002-09-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* WaitHandle.cs: Implemented WaitAll(), WaitAny() and WaitOne() as
	internal calls.

2001-11-26  Dick Porter  <dick@ximian.com>

	* Thread.cs: DataSlot uses a single system TLS slot, and a
	hashtable per thread.  Some minor changes to reflect the new
	internal calls using the new IO library, and the newly-supported
	bool returns from internal calls.

	* Monitor.cs: Use bool returns from internal calls now they are
