  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.
