Difficult.

I think you're looking for a way where you can restart the xdm master
process, and leave any other active-display-session process running until
the session is over.  Then it should die (not just reset (not sure if it
normally dies)), and the new master process should start a fresh process
for the display.

It is conceivable that you can't get any further than give a warning
that xdm should be restarted manually to prevent killing a user session.

Come to think of it, you may want to check with gdm, kdm, and
whatever-other-dm if they suffer the same problem.

Ciao.                                                            Vincent.
