	Added stack propagation when Thread.Start is called.
	* ThreadPool.cs: QueueUserWorkItem now does stack propagation (done in
	the runtime), so I "fixed" UnsafeQueueUserWorkItem not to do so.

	* CompressedStack.cs: Allow merging of an existing CompressedStack
	with the actual stack of the current Thread.
	* Thread.cs: GetCompressedStack and SetCompressedStack are public 
	before 2.0 but couldn't be seen with mono-api-info because of it's 
	LinkDemand for the ECMA public key. Removed unused CompressedStack
	private field (now part of the ExecutionContext).

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

	* CompressedStack.cs: GetCompressedStack is public before 2.0 but 
	couldn't be seen with mono-api-info because of it's LinkDemand for

	current thread.

	* Thread.cs: Optimize CurrentCulture to avoid initializing the
	serialization infrastructure in the common case when the culture is

	across appdomains. Partially fixes #50049.

2004-12-05  Miguel de Icaza  <miguel@ximian.com>

	* AutoResetEvent.cs (Set, Reset): If we are disposed, throw a
	ObjectDisposedEvent, helped track the WebConnection destructor
	issue.

2004-06-15  Lluis Sanchez Gual  <lluis@ximian.com>

	* Timer.cs: Don't abort the thread if Dispose() is called from the runner
	  thread.

2004-06-11  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* CompressedStack.cs: Added finalizer to match public API of
	MS.NET

2004-05-19  Lluis Sanchez Gual <lluis@ximian.com>

	  if the thread already has the lock. Added readyWaitingReaders variable to
	  keep track of threads ready to get the reader lock.

2004-04-11  Lluis Sanchez Gual <lluis@ximian.com>

	* LockQueue.cs: Moved lockCount change inside the rwlock lock. Removed

	* Timer.cs: call Abort on the Runner instance too.

2004-04-07  Jackson Harper  <jackson@ximian.com>

	* Thread.cs: Use new culture info method for constructing the

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.

	Fixes random errors caused by memory corruption.

2004-02-06  Zoltan Varga  <vargaz@freemail.hu>

	* Thread.cs: Implemented CurrentPrincipal.

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

	* Thread.cs: delayed thread creation until Start is called. If we
	don't do that and Start() is not called, the thread is leaked. First
	step towards fixing bug #53078. 

2003-12-02  Dick Porter  <dick@ximian.com>

	  thread's local data when switching between domains.

2003-10-08  Gonzalo Paniagua Javier <gonzalo@ximian.com>

	* ManualResetEvent.cs: added check for disposed.
	* Thread.cs: no need to init this field.

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>

	* WaitHandle.cs (CheckDisposed): This method is not in the public
	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>

	* ThreadPool.cs: correctly create a TimeSpan with provided the number of
	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

	a new field to support thread-static data.

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.
