Log message:
	Try to avoid inlining of ThreadInternal__StackGrowsDown, ThreadInternal__StackGrowsDownHelper
	by use of __declspec(noinline) or __attribute__((noinline)) on compilers
	that support them.
	
	In particular, if ThreadInternal__StackGrowsDownHelper is inlined,
	then the locals aren't necessarily "in the expected relative locations"
	and the return value could be wrong.
	
	We should probably #ifdef here to force the answer.
	e.g. x86, amd64, sparc, alpha, ia64, vax, etc., all always grow down
	e.g. hppa grows up
	
	We might also try inhibiting inlining/optimization by using recursion?
