You know... Thats why I was unsure...  The linux method is a new twist and
I hadn't thought of that, thanks Shawn. I'd have used the ready-made
routines
from Allegro if they weren't limited to milliseconds. I presumed the
limitation
was there for a very good reason. Heck, everything I read up till I asked
the
question talked about millisecond resolution timing... which was why I asked
if it was even possible in the first place.  As usual, I'm always trying to
do
something non-trivial... :-)
