"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.
