One thing to keep in mind about MacOSX is that the sleep
is *really* accurate compared to Linux, BSD and Solaris.

And also that this is mainly because for very small delays, Darwin
lets the "waiting" thread simply burn cpu cycles until the delay is
over (at least when I looked into this a couple of years ago). The
result is that very small delays are (were) quite inefficient from a
multi-processing perspective on Darwin (with the mentioned upshot that
they're pretty accurate).
