this presumes you care about responsiveness.  on some types of
systems, this is not an issue.

on the other hand, optimal scheduling also requires future knowledge
of CPU burst times, which is something a process is more likely to

trying to improve scheduling in this manner is rarely, if ever,
done. :)
