One worker per "hot table" seems like overkill to me; you could chew
up a lot of connections that way, which could be a DOS.

That you have a "foot gun" is guaranteed; I think I'd rather that it
come in the form that choosing the "hot list" badly hurts the rate of
vacuuming than that we have a potential to chew up numbers of
connections (which is a relatively non-renewable resource).
