This isn't a bad idea, as long as we don't use it as a crutch or
excuse. That is, answer scheduling problems with "properly nice your
tasks" -- the scheduler should be smart enough, to some degree.
FWIW, Solaris actually implements a completely different scheduling
policy, SCHED_INTERACT or something. It is for windowed tasks in X --
they get a large interactivity bonus.
