I have been testing this behavior in Firefox and it seems to also miss the onunload event if the window has not completely load. I am using a pop up window with a frameset for the content, closed it immediately on launch, and all my onbefore and onunload code was completely ignored. I know Firefox doesn't support onstop, is there any way to catch this on Firefox? This is a great fix.

But you will be able to use _ when IE6 dies. And the unload bug... yep, it's a tough one! Actually, the CSS part would be the _ as the first character of a class name and no, you can’t use – either.

And since that event never fires if the document never finished it's loading it can't cleanup the references. This is a common pattern in libraries. jQuery only listens for the unload event on that line.

So this seems to be one of those agonising "sometimes" bugs. I still have to test the load and unload events in my ongoing events research, so I'll test explicitly for this bug.
