bug#5552: 23.1; desktop seems not quite to understand session management

[rrt]

If I log out of my GNOME desktop then back in, desktop says that
another Emacs process (the old one) appears to be using the desktop
file and asks me if I want to use it anyway. If I say “y” then things
work as normal (unsurprisingly, since the old process is no longer
running). However, desktop should know that the old process is dead;
perhaps it needs to talk to the session manager code?
