Modified files:
	cm3/m3-libs/m3core/src/thread/PTHREAD/: ThreadPThread.m3 

Log message:
	Slightly cleaner version of suspended flag.
	This code should be safe because suspended is set to TRUE only while all other
	threads are stopped.  In effect it is private to the GC thread which stops all
	other threads before setting suspended to TRUE, and sets it back to FALSE
	before starting all other threads.
