Safari: jQuery 1.4.0 fails to fire the ready() event when navigating to pages via History stack

Description
In jQuery 1.4.0 release, Safari no longer fires the $(document).ready() event when navigating to a page via the history buttons (back or forward).
This is a change from version 1.3.x, which correctly fires the event.
Adding any unload event handler to the page will fix the problem (see http://stackoverflow.com/questions/158319/cross-browser-onload-event-and-the-back-button ); so I suspect this bug was introduced by preventing the "Prevent memory leaks in IE" code from running on other browsers.

This is very much intentional - attaching an unload will force the page to not be cached by the browser and it'll be reloaded (which is not good). This was actually a very beneficial change in 1.4. If you wish to have the ready even re-run then you should probably just attach the unload handler yourself.

Ah, I see I have improperly blamed jQuery for a different problem I am seeing: Safari is not re-establishing setInterval functions when the page is restored via the history buttons.
I can't find a bug to that effect on the WebKit tracker, but I can see from some testing that the issue is fixed in the WebKit nightlies.
Does not happen on Firefox/Mac or Chrome/Mac.
Re-enabling the window unload code on Safari fixes the problem, but possibly with some performance cost. A simple solution is to bind a noop to unload on Safari:
jQuery(window).bind("unload", jQuery.noop);
