Well, there's an ugly little BSD function called usleep(3) which uses 
the itimer stuff.

You can also use select(2) as in:

select(0,0,0,0,&sleepy_time);

(handle signals however you'd like...)


Many Un*xen will have select and perhaps the itimer stuff. Fewer
will have usleep (SYSV jocks have an easier time keeping up with
the BSD system calls...).

Bear in mind that this is all pretty grainy generic stuff. If you
want "real time" control you should look at something marketed
for it.
