Added to SVN. Good job Brandon!

The hotfix removes the custom unload events also. It's better to check if type == 'unload' before removing the event.

danyalex is correct. Here is an updated patch and example.

The example (you should get an alert onunload): http://brandonaaron.net/jquery/memoryleak2/event_leak_fix.html The diff: http://brandonaaron.net/jquery/memoryleak2/event_leak_fix.diff

Also this patch fixes a memory leak in Firefox related to the ready event. You can verify using the leak monitor extension vs this unfixed page: http://brandonaaron.net/jquery/memoryleak2/event_leak.html
