Given some of our (Chromium-team) recent investigation into the contents of unload handlers, I'm not sure how much this move will help users, even if you don't revert it. Lots of unload handlers busy-wait while doing async XHR in order to try to guarantee delivery of tracking pings. Authors will probably elect to copy this code to the pagehide handler rather than moving it, and the experience for users is still going to be extremely sluggish navigation out of these pages. PK
