[MLton] filedes = int (was: Stack size?)

I would probably just use nanosleep() for both.  There isn't much in the docs
to say that Posix.Process.sleep is the sleep() system call.  In fact, if  you
look at the libc code, for the sleep call it uses nanosleep().

The  only  thing  that makes me slightly (but only VERY slightly) nervous, is
the basis doc which says that sleep suspends until either  t  seconds  (note,
SECONDS) have elapsed.  Still, I say nanosleep() for both.
