That gets into a different set of questions, which is what we want the
buildfarm turnaround time to be like.  The faster members today produce
a result within 10-15 minutes of pulling their CVS snaps, and I'd be
seriously unhappy if that changed to an hour or three.  Maybe we need to
divorce compile/regression tests from performance tests?
