Modified files:
lib/libc_r/uthread pthread_private.h uthread_create.c
uthread_init.c
Log:
Don't explicitly mmap() red zones at the bottom of thread stacks (except
the initial thread). Instead, just leave an unmapped gap between thread
stacks and make sure that the thread stacks won't grow into these gaps,
simply by limiting the size of the stacks with the 'len' argument to
mmap(). This (if I understand correctly) reduces VM overhead
considerably.
