Comment(by ryan):

 The last_changed method used by terms was done to avoid the problems of
 the pages style caching where the arrays could get huge.  Currently, the
 last_changed method relies on old cache keys eventually being pushed out
 of the cache.  Using a timeout to reclaim them faster seems fine.

 I've yet to see flush by group (or even just flush) implemented solidly
 for all of the various cache backends for both WP and WPMU.
