I guess I'm in the minority here, but I don't see why it isn't useful
to have something like this. It's a lot easier for a monitoring
process to poll for this kind of thing than it is to monitor the logs.
Not that log monitoring isn't a good idea, but this is pretty
lightweight.

OTOH, it also seems like this could live as an out-of-core extension,
so I guess if nobody else likes the idea Anastasia could always do it
that way.
