	  exitContext is true.

2004-04-08  Gonzalo Paniagua Javier <[email protected]>

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

2004-04-07  Jackson Harper  <[email protected]>

	* Thread.cs: Use new culture info method for constructing the
	current culture.
	
2004-04-07  Lluis Sanchez Gual <[email protected]>

	* 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 <[email protected]>

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

2004-04-06  Lluis Sanchez Gual <[email protected]>

	* 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 <[email protected]>

	* ThreadAbortException.cs: use same HResult as MS.

	* Thread.cs: Implemented CurrentPrincipal.

2004-01-22  Gonzalo Paniagua Javier <[email protected]>

	FreeNamedDataSlot.

Wed Aug 20 12:01:36 CEST 2003 Paolo Molaro <[email protected]>

	more fields needed by the runtime.

2003-08-14  Lluis Sanchez Gual  <[email protected]>

2003-07-23  Duncan Mak  <[email protected]>

	API, mark it as 'internal'.

2003-07-01  Dick Porter  <[email protected]>

	(Better than just blowing up later.)

2003-06-25  Dick Porter  <[email protected]>

	milliseconds.

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

2003-06-06  Gonzalo Paniagua Javier <[email protected]>

	* WaitHandle.cs: checks and exceptions.

2003-05-31  Gonzalo Paniagua Javier <[email protected]>

	* 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 <[email protected]>

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

	a new field to support thread-static data.

2003-04-17  Pedro Mart�ez Juli� <[email protected]>

	* 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  <[email protected]>

	* 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  <[email protected]>

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

                    model more equal to the MS one.

	* 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  <[email protected]>

	* 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 <[email protected]>

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

2002-10-25  Zoltan Varga  <[email protected]>

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

2002-10-24  Gonzalo Paniagua Javier <[email protected]>

	* 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 <[email protected]>

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

2001-11-26  Dick Porter  <[email protected]>

	* 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
	supported by the runtime.  Coalesce enter with the try_enter
	internal call.

Wed Nov 14 17:06:18 CET 2001 Paolo Molaro <[email protected]>
