Yes, at the cost of throughput, however for now it is probably
the best way to go. Hopefully anticipatory scheduling will provide
as good or better kernel compile times and better throughput.

Con, tell me, are "Loads" normalised to the time they run for?
Is it possible to get a finer grain result for the load tests?
