Interesting results.

It'd be nice to see what difference the changes since .31 have made to
these comparisons. In particular, child_runs_first was found to have a
substantial negative impact on parallel compiles, and has been turned
off. The reduction of sched_latency has a rather large effect on worst
case latency for CPU hogs, so will likely affect some results markedly.

Hohum, back to the grindstone.
