    # 
    # The eventing subsystem will need to be extended to support 
    # onsuccess and onfailed callbacks. 
    # 
    # Currently, this call may go to a Persistor.fetch() that 
    # collects data from a DB,file,thing. 
    # 
    # If that call takes long, it holds up the entire EventMachine 
    # reactor.
    # 
    # Ideally:
    # 
    # - In the case of a TCP based system, with a ACK based protocol, 
    #   this call should be deferred into a Proc with callbacks to
    #   on_success and on_failed
    #
    #
    #   ...to be continued.

  # These trigger calls fail in test,?
  # but work in RL

  # Dunno why...

  # 
  # @protocol.accumulate( multi_message_part, self )
  #
  #   ---- With protocol responding directly to source
  # 
  #   ---- With protocol then calling receive_decoded()
  #        via the self being passed in.
