I think this output from ps makes it all clear:

dissent    919   ?        S    20:52   0:00 wterm -tr -tn xterm
dissent    920   pts/2    S    20:52   0:00  \_ zsh
dissent    942   pts/2    S    20:53   0:04      \_ xemacs -vanilla
root       957   pts/4    S    20:54   0:00          \_ /bin/sh

So, su is exec()ing itself away.

I experimented on an older system I have, and su doesn't use
exec() there.  Consequently XEmacs exits normally.

Hmmm, I have no idea which su I'm running.  It's not the GNU one,
because it doesn't support --version.  My older system runs the
GNU one.

So a changed su is to blame.  Do you think it should be raised
with the XEmacs people?  (What about GNU Emacs?)  I'm not sure
that you want to change TRAMP.  Maybe I'll report the problem to
Debian too and see what they say. . .
