There are ways to get sub second sleeps in Sys V 3.[0|1], using a serial
port. I've had no problem getting 1/10 second sleeps on any of Bell,
Microport, or AT&T. If you're running an older version (pre 3.2), and want the
code, drop me a line; it's only a few dozen lines long. I didn't notice
that nap() was in the 3.2 lib; I'll have to look. Is that nap() as in
curses napms()? If so, even tho' you specify time in milliseconds, Sys V
rounds to normal sleep() intervals (in fact, that's what most curse's
napms() actually calls).
