Comment:

 It isn't likely that a low-traffic site is using a persistent cache, so
 the concern of (1) is minor. In the case of a persistent cache, we could
 schedule an event, yes, but we could also try to store a "lock" in the
 persistent cache store. Whichever process successfully sets the lock gets
 to run the query, and until the query is complete, the old cache gets
 used. Just an idea.
