In fact, I accidentally sent the wrong (previous) version of the patch. I mentioned that while getting ready to send the correct version, I noticed another race window. I am currently finishing some testing on that. Bottom line is that this patch should not move forward. A new version will be sent and I will attempt to answer your questions about introducing a performance regression. Sorry for any confusion, -- Mike Kravetz
