I have a question now. In rwlocks, your algorithm doesn't bump spin_cnt for the adaptive spinning in read mode. Is that intendend? I don't think so, probabilly we should fix it by bumping spin_cnt also in the adaptive spinning in read mode. Thanks, Attilio -- Peace can only be achieved by understanding - A.
