New description:

 We've a few occurrences of things such as:

 {{{
 wp_cache_add( $cache_key, $terms, 'terms' );
 }}}

 ... in taxonomy.php. These are not flushed when the terms cache gets
 flushed, and end up stored in memcached indefinitely. We should at least
 add a timeout, maybe after a day.

 Better yet, we should flush them properly.

Comment:

 I've been working with the patch applied for a couple days. No side
 effects apart from the obvious extra query per day.

 @Ryan: do you need it massaged any further?
