Yes, but how does libqof gain access to that?  At that point we might
as well just have:

   void qof_event_register_base(GObject*);

And let the application deal..

Well, I think the point was that every Qof object would derive from
gobject.  At least that's what I had in mind.  So, yes, a QofSession
would be derived from GObject.  The only remaining question is whether
we would want cross-session events, or if we need an event when we
create a new session?

Again, I think we need to really think hard about how we want events to
work.  Do we want events passed up the stack?  How do we make sure that
a signal handler doesn't eat a signal?
