I'd like to get some regression testing (standard macrobenchmarks) in
on the scheduler class bits in isolation, as they do have rather
non-negligible impacts on load balancing code, to changes in which such
macrobenchmarks are quite sensitive.

This shouldn't take much more than kicking off a benchmark on an
internal box at work already set up to do such testing routinely.
I won't need to write any fresh testcases etc. for it. Availability
of the test systems may have to wait until Monday, since various people
not wanting benchmarks disturbed are likely to be out for the weekend.

It would also be beneficial for the other schedulers to be able to
standardize on the scheduling class framework as far in advance as
possible. In such a manner comparative testing by end-users and more
industrial regression testing can be facilitated.
