If we're going for matching what browsers do, there's a number of cases
(different in each browser) where the confirm doesn't popup. In Chrome, for
example, if the beforeunload handler takes too long, we kill it and navigate
away. Similarly, in Firefox, if the beforeunload handler hits the limit for
script execution and the user stops the script, the beforeunload handler
never fires.
Not sure what the right language for that is. But developers try to do
things like using beforeunload/unload to release locks, make server
requests, etc. and it's just not a very reliable thing to do in any browser.
It's really just useful for the quick prompt for the user as to things like
unsaved changes.
Here's a fun one, I made this as a demo to show how a website could trap a user
forever:

I haven't tried it in any browsers lately, but a quick test with IE7 shows it
still is effective (for it at least).

I've tested it 'en passant' with FF3: I want my base back!!!!!!! LOL
