Adding to this, I think the reason is that the call to x_session_close() in
x_delete_display() deletes the connection's FD, but does not actually tell the
SM to close. Adding a call to SmcCloseConnection() to x_session_close()
solves the hanging behaviour for me, but of course retains the weird behaviour
of Emacs not shutting down if the first terminal was closed.
