 Modified Files:
 	src/tests/lib/libpthread: t_stack.c
 
 Log Message:
 libpthread/t_stack: Make this more robust to the guard size bug.
 
 Make sure to allocate enough space for the thread's stack for a guard
 even though there shouldn't be one, so that when we run the thread,
 it doesn't start with the stack pointer pointing into someone else's
 allocation (like malloc) causing stack frames to trash another data
 structure -- or causing the user of that data structure to trash the
 stack frames.
