[issue29947] In SocketServer, why not passing a factory instance for the RequestHandlerClass instead of the class itself?

New submission from Dominic Mayers: I am just curious to know if someone considered the idea of passing a factory instance that returns RequestHandlerClass instances instead of directly passing the class? It may affect existing handlers that read non local variables, but there should be a way
