In the Python subprocess, RPCServer is instantiated with handlerclass
MyHandler, which inherits register/unregister methods from RPCHandler via
the mix-in class SocketIO.
When the RPCServer 'server' is instantiated, the TCPServer initialization
creates an instance of run.MyHandler and calls its handle() method.
handle() instantiates a run.Executive object, passing it a reference to the
MyHandler object. That reference is saved as attribute rpchandler of the
Executive instance. The Executive methods have access to the reference and
can pass it on to entities that they command
(e.g. debugger_r.Debugger.start_debugger()). The latter, in turn, can
call MyHandler(SocketIO) register/unregister methods via the reference to
register and unregister themselves.
