  71  * The first time a client requests a pointer to an interface on a
  72  * particular object, COM loads an IClassFactory stub in the server
  73  * process and uses it to marshal the first pointer back to the
  74  * client. In the client process, COM loads the generic proxy for the
  75  * class factory object and calls its implementation of IMarshal to
  76  * unmarshal that first pointer. COM then creates the first interface
  77  * proxy and hands it a pointer to the RPC channel. Finally, COM returns
  78  * the IClassFactory pointer to the client, which uses it to call
  79  * IClassFactory::CreateInstance, passing it a reference to the interface.
  80  *
  81  * Back in the server process, COM now creates a new instance of the
  82  * object, along with a stub for the requested interface. This stub marshals
  83  * the interface pointer back to the client process, where another object
  84  * proxy is created, this time for the object itself. Also created is a
  85  * proxy for the requested interface, a pointer to which is returned to
  86  * the client. With subsequent calls to other interfaces on the object,
  87  * COM will load the appropriate interface stubs and proxies as needed.
