I have narrowed it down somewhat. Unfortunately, the actual leaks are not
necessarily 100% reproducible, but that may be because the page content changes
regularly. Having just the:
feed://images.apple.com/trailers/rss/newtrailers.rss
url open from the autoclick book mark gives a small set of leaks:
sw-90-731-860-3 82 % leaks 12212

Having just the Google news url (http://news.google.com/) open from the
autoclick book mark also gives a small set of leaks:

However, having both of them in there:

http://news.google.com/
gives a much larger set of leaks:

I then thought to check, are there any leaks if I do nothing? So, open Webkit
nightly, which redirects to page checking build number, set Private Browsing,
turn off back/forward cache, and close initial window:

so some of those leaks above are possibly due to this initial window's opening.
I guess if those are fixed, I can retest the autoclick bookmarks to see if
there are still any leaks. Hope this helps.
