reload: Catch exceptions aborting pending AJAX requests.

Browse Source 
It's probably a bug that this throws exceptions sometimes, but it's
not consistently reproducible (or maybe, browser dependent?), and it
isn't really a problem to fail to abort some requests as part of the
page reload process; the abort was just there to make sure as little
as possible is happening so we can garbage-collect effectively.
