[omniORB] basic parameter passing question

[Anthony Shipman]

A server of mine has an object reference stored as:

isdn::BChannelControlClient_var	ctlObj_;

isdn::BChannelControlClient_var&
BChannel::getControl()
{
    return ctlObj_;
}


A method of an interface wants to return this object reference. 

isdn::BChannelControlClient_ptr
Service_impl::new_client(...)
{
   ...
   return isdn::BChannelControlClient::_duplicate(bchan->getControl());
}

The Michi+Henning book says that the caller of new_client() is responsible for 
releasing the returned object reference. This says to me that I must
duplicate the reference before returning it. Is this correct?

With omniORB 4.0.5 I find that there is a memory leak. I'm told that the leak 
goes away if I return the reference like this.

    isdn::BChannelControlClient_var retval = bchan->getControl();
    return retval._retn();

As far as I can tell this code should be exactly equivalent to the use of 
duplicate. Does this make sense to anyone?
