In the OS9 operating system, you can sleep for a granularity of
1/10 sec, or on the Color Computers, 1/60 sec.
The C library sleep() only allows 1 sec resolution,
but a general system call lets me get the 16.7 ms resolution
on my Coco.  I use it to play MIDI music, so I know it works;
I've *heard* it work.

Moral: Don't confuse what the C Std Library (or any other lib)
gives you with what the underlying OS is really capable of.
Portability?  Bring friends.  Big strong friends....
