basically, if you and I both write programs to do a particular job
on a timesharing system, and you use threads to do so and I use
a sophisticated event handler/state machine, I shouldn't find that
my program is running like a pig because yours has 1000 slots in the
run queue and I only get run 1 in 1001 ticks.
