The trouble is that the socket directory needs to be created before ssh
tries to forward the socket.  when doing a forward from the command
line, the ssh channel that does socket forwarding is often established
before the channel that runs any shell or other interactive behavior.

I really think this ought to be handled in OpenSSH.
