POA Initialization

When a POA is instantiated, it is put in a holding state - it will queue any requests it receives (up to some implementation limit). This allows the programmer to register all servants with the POA, before starting to process requests.

The Root POA, however, is not instantiated directly. We need to request its object reference from the ORB. This is done using the ORB's resolve_initial_references method. This is the ORBs bootstrapping method.
