If I delete a Category page, and no articles refer to the category, it still shows up in the category tree, until the user logs out and back in.
Hmm... with no page record there'd be no page_touched timestamp to update the cache... :(
Well, if a page is deleted, all category pages showing it have to be purged, right? So the cached bits for CT could be purged in the same way. Sadly, I have no clue whatsoever how that works.
Perhaps the ArticleDeleteComplete hook could be used with a custom job class?
