----------------------------+--------------------------
 We have started using one cache bucket per query with passive invalidation
 controlled through a last_changed incrementor. See #22024 for an example.
 We also need to do this with get_pages(), wp_get_archives(), and
 elsewhere. On wordpress.com we have hacked some of these into separate
 buckets because saving multiple queries per cache bucket results in huge
 buckets. We have seen 72MB get_pages caches. Let's finally clean this up
 for good. Some of the last_changed work done for #22176 can be used here.
