Closed connection errors with the new Gnus

[Stefan Monnier]

Since we switched to the new Gnus, I tend to get errors about the server
closing the connection.  I'm assume such disconnections happened before as
well, but they were handled transparently.

See the backtrace below (which is all I can offer just now).  Anybody knows
what's going on?  Is it just a matter of a failure to catch the error and
reconnect&retry?
