Just emacs.

It has to do with me switching over to LANG=en_CA.UTF-8, and that the
iso10646 fonts are being served by xfs on the GNU/Linux box.  From an
xterm (client on GNU/Linux, either Xserver, tripe is the w32 host)

   DISPLAY=tripe:0.0 LANG=en_CA emacs -Q         # No problem
   DISPLAY=tripe:0.0 LANG=en_CA.UTF-8 emacs -Q   # Hangs

Or if I take the xfs off the w32 X server's font list then

   DISPLAY=tripe:0.0 LANG=en_CA.UTF-8 emacs -Q   # No problem

I am using 'emacs*font: fixed' for my .Xdefaults.
