Comment (by _timk):

 I've also tried John Resig's jQuery profiler (http://ejohn.org/blog/deep-
 profiling-jquery-apps/), but it doesn't record the massive delay.

 To me, that's further evidence that it's a page unload problem. The
 profiler resets anew when the page is reloaded; I'd need to somehow cancel
 the page unload after the delay, which I don't know how to do.  I tried
 hooking into things like the window unload and onbeforeunload events, but
 those trigger before the script becomes unresponsive.
