What's happening is that the set_servant_manager call is doing a _narrow
on the ServantManager object behind the scenes, to make sure it is the
right subclass (ServantLocator in your case). The _narrow involves a
CORBA call to the _is_a operation, which goes through the POA. You
haven't activated the Root POA (where the ServantLocator is activated),
so it blocks waiting for you to activate it.

All you need to do is activate the Root POA's POAManager before calling
set_servant_manager, and it will work fine.
