When a snapback page is set, the WebKit back/forward cache (AKA page cache) can grow without bound, 
because it will find the oldest back/forward item but will refuse to actually purge it since it is marked as 
the snapback item. A simple fix would be to purge the most recent non-snapback item when the page 
cache goes over its maximum size instead.

Whoops, I left debug code in the last patch.
