// raise exceptions, but I'm undecided.
// @@ Pradeep: when is the child poa destroyed? Maybe we should add
// a destroy() method to the factory interface (in IDL).
// @@ Carlos: if we add a <destroy> to the factory, any client will be
// able to destroy the factory!
// @@ Pradeep: it could be a method of the Factory_i class, it
// doesn't have to be exposed through the IDL interface. Anyway,
// there must be a way to cleanup any resources created by the
// factory, and you must avoid CORBA calls in the destructor,
// first because you won't have an ACE_ENV_SINGLE_ARG_PARAMETER and second because
// exceptions in destructors are evil.
// @@ Pradeep: anyway you can just use exceptions and not return -1?
