Not under OS X it isn't.  I started a thread about this last year:
there's no way to sleep with a granularity of less than 10-15
milliseconds.  The group discussion pinned this on the underlying
operating system, which I'm not sure I buy.  Rather horribly, I
resorted to a busy wait loop that continually calls now/0, which works
perfectly, but sure causes the fan on my MacBook to spin up.
