hmm, now there I'm reading this i realize it, too. Any better solution
in mind? On the other hand, when you manually close a session, normally
only stuff like pager, tray, panel, desklets are running, the rest is
closed by you before that. That's why I choose delete-window-safely, as
it would be enough for that windows.
