docstring: Start the Python execution server in a subprocess
  
      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.
