See sched_yield.

We could implement it, but I suspect that most who use it also use the
rest of the sched_* POSIX scheduler control functions, which are
probably not reasonable for DJGPP to implement.

On some systems, but I think not Linux, sleep(0) yields the current
timeslice.

But in general, if you need it, you're probably polling for some event,
which is probably a bad idea.  What is it you're trying to do?
