You may also lose the connection. With older versions of OpenSSH, I frequently
see the client complain of a "truncated packet" (SSH has its own internal
packetized protocol) and drop the session. Sometimes this is just a minor
inconvenience -- for example, if I'm doing POP over the forwarded port I
sometimes find that the mail client becomes confused and/or does not filter
incoming messages properly. It's a bigger concern if I'm doing administration
and am cut off in midstream.
