It's not useful to send the output to the zle file descriptor; it can't
be redirected and it causes a crash in a subshell.
I presume the most obvious thing is to send all expected messages to
stdout. However, there's an argument for messages from the verbose
options to go to stderr (which is what I originally wrote before
realising it could be surprising).
Another problem I've noticed, not fixed here, is that at the moment it's
not possible to recover cleanly if someone else comes along and closes
your fd's. They shouldn't, but it should be possible to remove the
sessions none the less. Further, if you then attempt to unload
zsh/net/tcp, the shell gets left in an inconsistent state and another
`ztcp' causes a crash.
