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

Log message:
	me.stackbase := NIL inside activeMu, so that dying threads
	aren't suspended/resumed
	
	I tried making suspend/resume always succeed if stackbase = NIL,
	but that access violated in StopWorld; I don't understand.
	
	That is, setting it NIL outside the locks should be ok, as long
	as the code inside the locks notices.
	
	Test case if starting Juno on I386_FREEBSD with gcc 4.7 backend.
	It doesn't reproduce under a debugger.
	
	Note that probably FreeBSD, x86, gcc 4.7 aren't relevant.
	What probably is relevant is that Juno creates many threads
	and probably much garbage and heap allocations during startup.
