So, unsurprisingly, I got some _really_ good results on the epoll_wait() benchmark by removing the readywalk list altogether -- something like 4000% in some cases. It's also survived more testing, although I'm still waiting for customer confirmation on his real workload, which helps further test the changes (along with this patch to move the safewake list to debug). Could you please resend patch 1 in the series above? Thanks, Davidlohr
