Also, I have to hit C-g after the error appears, which is a little
odd.

But more importantly, I also found that I'm unable to exit Gnus after
this error occurs.

It would be better if I could proceed without reconnecting, but since
I can't become unplugged, I am unable to read *any* of my groups using
the agent (not even groups from other servers).

I think J j should bring me to the unplugged state, even if the
connection is already down.
