that can be tricky to do directly from a signal handler because it can
involve deleting the object for which the signal is being emitted. GTK
(and gtkmm and sigc++) don't respond too well to this kind of thing.

when the window manager initiates this, all the "extra signal handlers"
do their stuff and if none of them indicate that the signal has been
handled, GTK completes the task *outside* normal signal handling scope.
