Modified files:
	cm3/m3-libs/m3core/src/thread/WIN32/: ThreadWin32.m3 

Log message:
	Like pthreads, have Thread.T derive from MUTEX, so we can LOCK it,
	instead of using one global threadMu for the fields of all threads.
	
	Note that Win32 Modula-3 threads/mutexes still scale well due to the
	the critical section cm that guards everything. Probably can't be
	fixed until there is a version that depends on the condition variables
	introduced in Vista.
