indeed it could be a valid use case; but not without a constraint, just imagine I wanna close my browser and your sync onunload() request would take 5 secs to be processed by server - what happens then? its evil!
imho, if you want to process the response afterwards, like printing it out to the user, anyway you should convince him about it - so the user is not surprised that his browser gonna hang for few seconds. and here you can alert() him about that, or even acquire a confirm()ation - in both cases you can use it as an sync point on the browser while processing async request....
