Dan, I hope you will release these as a patchset against 2.6.22 when
it's out or 2.6.21. I find I have a lot more confidence in results, good
or bad, when comparing something I have run in production with just one
patchset added. There are enough other changes in an -rc to confuse the
issue, and I don't run them in production (at least not usually).
