NAK. If we have disconnect messages (NBD_OPT_ABORT and NBD_CMD_DISC), it
makes sense to say that clients should use them. Protocol violations by
peers are a different matter; but in the general case you should drop a
connection properly, i.e., by using the relevant "close the connection"

(I realize I didn't comment on this earlier, but I changed my mind
during the discussion about DISC).

< ron> I mean, the main *practical* problem with C++, is there's like a dozen
       people in the world who think they really understand all of its rules,
       and pretty much all of them are just lying to themselves too.
