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