guaranteed the delivery of *some* notification, but possibly one
containing less information than what was sent. Or you might get
a notification when in fact none was sent. This should be okay
for ordinary uses of NOTIFY, as long as such cases are infrequent
(so that you don't waste many cycles checking for events that
didn't happen).

TIP 2: you can get off all lists at once with the unregister command
