You can get an idea of how much time is used by the OS. On my computer I look
under Task Manager and it says:

Image Name		CPU Time
System Idle Process	6:19:14
IEXPLORE.EXE		0:02:16
msdev.exe		0:01:22
Explorer.exe		0:00:53
System			0:00:22

And so on. So I have over 6 hours of idle time, and the next biggest chunk of
CPU usage time was by Internet Explorer, of a whole 2 minutes. That means there
is 99.5% of the CPU time that could have been used by a chess program. So the
question is whether or not a 0.5% increase in speed is going to mean
"significantly better" results. I think not.
