Ship it!




Interesting!
I have a few local patches like this that I haven't pushed, because applications that don't need to be restored by the session manager don't care whether they are killed before they are saved for sesson restore, right? I had a suspicion that something might still be wrong which is why I still have those patches, waiting to push them in case they turn out to be useful :)
Of course, in the cancelled logout scenario, one does care about applications getting killed too early and this fixes it.
This one is yours, I'll push the other ones.
