[M3devel] RC merge

[Jay K]

Correct ThreadWin32 not ThreadPThread or ThreadPosix.
I narrowed the problem down to a 30 minute window in Februrary (see older mail).
I'll try again with recent changes (esp. if they are in common code, which I don't think they are)

That's ThreadWin32 right?

  Tidy up use of thread.inCritical to only occur in allocation sequences and in
  thread stoppage.  This simplifies reasoning.  Refactored use of heap lock
  in the process.  This may be better implemented on PTHREAD targets using a
  recursive pthread mutex instead of one we roll ourselves from a non-recursive
  mutex.

  Still witnessing random hangs in Juno and mentor on I386_DARWIN.
  Strange, I thought this was working previously.
  I wonder if there is some sort of race in the GUI code somewhere?

No, the hangs in Juno and mentor are no longer there.  I cannot reproduce them on I386_DARWIN.

How does one do it easily?
I wish we used Perforce. :(

Can someone merge my recent deep fixes to pthreads threading over to the release branch?  I won't get a chance to do so until next Monday at the earliest.
