Re: gconfd-2 does not exit when a user log out, breaks unmounting home

Your second solution may be something that could be generalized to be
quite useful -- perhaps freedesktop.org material?  Other projects,
like the venerable esd, have problems similar to gconfd.  Esd can lock
down a system's audio device for a while after a user logs out.  I'll have
to spend a little time looking at xscreensaver, gnome-settings-daemon,

Your first solution seems simple enough.  I included a very unsophisticated
patch that performs the task (vs. gnome-session 2.4.0).  Comments?
