Actually, I've found out some email that answers some of my questions:

If I am not mistaken, every Servant that inherits RefCountServantBase
and then uses rootPOA.deactivate_object() in a "destroy" method gets
destructed automatically, right?

The following questions are still unanswered.

Thanks a lot for your help again,
