In the application that I'm developing, I do use the onbeforeunload
event and it works well for me. I do a check against the data that's
being worked on, and return an error message for a JS alert if it
hasn't been saved. The speed is exceptionally fast, but if you have
concerns you can preemptively pop up an alert and ask them if they
really want to quit, while in the background doing whatever AS stuff
you want.
