Well, a web page CAN intercept the "going away" events, and decide to
1) save the data, or 2) warn the user, and cancel the event. (Zimbra
does this)

OTOH, there is some way to save state information, since Google Mail does it.

OTGH, Google's programmers are probably smarter than average
(including me), so it may take a lot of effort to do so.
