This will be used in the proxy to multiplex one plugin across multiple renderer processes. We need the instance in the proxy to know which process to send it to. I added a deprecated var object creation function for native client, which depends on the module and this is very difficult to change. Because it doesn't have the multiplexing requirements, this is fine for now.
