/* From: http://msdn.microsoft.com/library/en-us/com/cmi_m_4lda.asp
*
* The first time a client requests a pointer to an interface on a
* particular object, COM loads an IClassFactory stub in the server
* process and uses it to marshal the first pointer back to the
* client. In the client process, COM loads the generic proxy for the
* class factory object and calls its implementation of IMarshal to
* unmarshal that first pointer. COM then creates the first interface
* proxy and hands it a pointer to the RPC channel. Finally, COM returns
* the IClassFactory pointer to the client, which uses it to call
* IClassFactory::CreateInstance, passing it a reference to the interface.
*
* Back in the server process, COM now creates a new instance of the
* object, along with a stub for the requested interface. This stub marshals
* the interface pointer back to the client process, where another object
* proxy is created, this time for the object itself. Also created is a
* proxy for the requested interface, a pointer to which is returned to
* the client. With subsequent calls to other interfaces on the object,
* COM will load the appropriate interface stubs and proxies as needed.
