I am using emacs in server mode on a remote machine. The intent is to
have a persistent emacs session that I can reconnect to.

Here are the steps I typically do:
% ssh <machine>
% tmux attach (This step doesn't seem important. I've tried this with and
without tmux).
% emacs --daemon
% emacsclient -n -c
% tmux detach
% exit

At this point the server is toast.

I am using cygwin on Windows 7 for the ssh client and X server. I have
also tried emacs 24.5 with no success. I have tried multiple X tool kits
(athena and motif) with no success.
