What is the big difference between alerts from unload and alerts in general? 
Alerts are not particularly useful for anything besides debugging, and 
pagehide/unload handlers is a place where they I've found them particularly 
useful for debugging.

Do we have at least anecdotal evidence that many sites are showing alerts from 
unload? When I'm seeing a site that tries to prevent me from leaving it, it's 
always by returning a string from onbeforeunload.
