  NSThread's sleepUntilDate will do what you want to do.  You could
also call the bsd call "sleep" directly.  Type man 3 sleep for
details.

RE: how long to sleep.  It very much depends on what your doing and
how fast you want to do it.  I'd suggest you code it up and
experiment with values until you find a balance your happy with.
