We should see if there are things that can be done to improve the perception of speed when the user is about to close a tab.
Eg.
- can we prepare the tab that will be displayed next by removing any throttling of JS there?
- if the next tab is a lazy browser after a session restore, should we start loading the page in it?
- can we reduce the priority of the current tab's JS so that we have more resources available for the next tab that will be shown?
- how badly would we break the web if we fired the onbeforeunload even on mousedown on the close button rather than on click?

Bug 1430292 applied some of this idea with tab warming, but comment 0 has more ideas that might be worth pursuing, so let's keep this bug around.
