23.1; desktop seems not quite to understand session management |
|

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?

When you log out, the X connection is closed and emacs exits.
However, it does not run kill-emacs-hooks. Desktop.el depends on that
hook to clean up after itself.
Should we run kill-emacs instead of shut_down_emacs when exiting due
to X connection lost?
There was a related thread about this a year ago, regarding how Emacs
responds to SIGTERM by calling shut_down_emacs rather than kill-emacs:
http://lists.gnu.org/archive/html/emacs-devel/2009-01/msg00530.html
The thread did not have a clear conclusion, but I'm in favor of changing
things to run kill-emacs in such situations. But I think this is best
done after the release, unless someone can come up with a very
convincing argument otherwise.
kill-emacs is now run in Emacs 24 when X connection is lost, when SIGTERM or
SIGHUP is received (Gnome session management uses SIGHUP to kill X clients).
