I wonder it's really safe.  If we create a lot of threads like Java
EJB environment, we consume virtual memory four times faster than the
current implementation.  You find STACK_SIZE is a boundary for each
thread.  The right way is to support floating stack (thus libc6-686)
or nptl + tls, I think.  I'm afraid this patch affects badly.
