The only time Sleep does not release its timeslice is when its argument
is 0 and there are no other qualifying threads waiting to be scheduled.
With a non-zero timeout, Sleep will release its timeslice, and it will
not be awarded another timeslice until at least that many milliseconds
have elapsed. If there are no other qualifying threads in the meantime,
then I don't know what happens, but that's for the OS to determine.
