Comment(by filosofo):

 I don't think the get_pages() approach scales very well.  I've noticed
 several times that sites with a large number of pages at points exhaust
 the available memory in one of the cache methods. Since for a typical WP
 site there are many more terms than pages, I'd expect this to crop up more
 often if used for terms.

 Why not do something like I suggested a while ago: #4476.  Delete cache
 items by group name.  Then the clean_term_cache() could just flush all
 members of the "terms" group.  Problem solved, right?
