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.
