There may be a problem that objects with slots can persist into new
sessions (i.e. be saved) but I think connections die when a session
ends, so whatever is in the slot is no longer valid.

automatically.
I'm not sure I understand your point here. Having multiple objects refer to
the same connection seems like a perfectly reasonable and useful thing, and
garbage collection should work just fine -- when *all* of the objects
referring to that connection are unreachable, then the connection is
unreachable and will itself be garbage collected. No?
