First some precisions. The problem seems to only appear when the X server is killed while the login screen is displayed.
I compiled xdm without the patches debian/patches/*.diff $ :>debian/patches/series and tested it. The problem does not appear anymore i.e. the file /var/run/xdm.pid remains after a kill of the X server while the login screen is displayed. But when one stops xdm $ /etc/init.d/xdm stop ... (...removing stale pid file...) a surprising message is displayed and xdm is killed nonetheless. Does one of the patches fixes this possible problem? There are thus indications that the problem comes from a Debian patch. So if it is not to be fixed, please mention it in the README.Debian. Incidentally I noted that xdm cannot bear two X server kills while X server is displaying the login screen. After the second kill the X server is not restarted anymore. The man page of xdm does not describe the behaviour in such a case. I see this as a bug, maybe related to this one, maybe not. Should it be reported somewhere else?
