Unfortuantely we don't have a proper mechanism to restart programs in
the desktop session. Using killall in postinst is something I'd be wary
about.

Unless someone finds a way to make gnome-shell (and g-s-d) compatible
with the older versions, I guess the best we can do is to show a NEWS
entry. But that is typically only read by the admin.

update-notifier would be another option, but I'm unsure about it's
current state in jessie and if it actually still works.

And last, it wouldn't work for Josh's case either, who locked the screen
midway through the upgrade.
