Ah, it is in glibmm-2.6 that I have a tarball of here.  That method is
invoked in the destructor of Glib::DispatchNotifier, because in that
version of glibmm, Glib:DispatchNotifier is not derived from
sigc::trackable.  However that is not going to save you (any more than
sigc::trackable will) because as I have mentioned the
Glib::DispatchNotifier object appears to be a thread-local static
object, shared between all Glib::Dispatcher objects created in that
thread.

I am now definitely off to bed.
