I just looked it up in the Pickaxe... you're right.  It returns the
time actually slept (rounded to the nearest second) and tries to sleep
to the specified float time.

This is not meant to a precise I don't think, so this kind of round is fine.

I once needed greater precision than sleep() but I forgot what I used.
 I am pretty sure there is something in the standard library for this,
though.
