Henk de Groot has been keeping me informed of such things.  I think
he may do a bit more work on getting that CPU usage down on Cygwin.
I have a hard time finding test machines to do it with.

If you get a chance though, crank up "nexttime" in
main.c:UpdateTime() to see if it helps on Cygwin.  Henk was doing
some of that and got it down to 30% or so.  If you can do a bit more
and track down where the CPU is really getting used, that'd be even
better.  We can put in Cygwin-specific delays once we find the
culprit, or code around the problem.
