There's no actual 'housecleaning' per se, just lazy expiration and eviction. If an item's expiration time is reached, the next time its key is requested, the lookup fails. If the server is out of memory, it'll evict expired items first, but if nothing's expired, will start evicting things in a least-recently-used fashion. More info is on the Google Code wiki:
