 When there's no persistent object cache in place, WordPress uses the
 options table to store transients. We should introduce garbage collection
 to avoid stale data sitting around indefinitely.

 This should be fairly straight forward to implement. A daily cron schedule
 would fetch all options with a key that begin with `_transient_timeout_`
 and a value that's less than the current time, then clear all the matching
 transients.

 Any objections? I'll patch it up if not.
