Yes and no.

Yes: The original bug report was about a server getting "stuck" if we didn't
send ABOR, so theoretically it still hangs on the connection if we just close
it. So sending ABOR is the nice thing to do to the server.

No: That occasional hang will not bother us somce we just proceed and close
down the entire thing anyway without trying to read anything further from the
command connection.

As we now send ABOR my only concern is if there's another case that we haven't
yet thought of or ran into that makes sending it a bad idea, as otherwise I
think sending it makes sense.
