"sleep" has always been approximate.  If you issue a "sleep X" command, all that 
you can count on is that you sleep for at least X seconds.  We shouldn't 
document the internals of how "sleep" accomplishes this.  That being said, it 
might make sense to say "sleep is approximate", if we're not saying it already.
