Sorry, NOTIFY -- not NOTICE (damn keyboard...)
Right now we're required to do a select against the database
periodically which means a test is required before hitting any cached
elements. By the time you select true, might as well do the real
select anyway (normally simple index lookup).
The ability to receive one without making a query first would be very
advantageous.
