    #
    # Add a idle processing message to be sent to a target object when
    # the system becomes idle, i.e. when there are no more events to be processed.
    # There are several forms for #addChore; the original form (from FOX)
    # takes two arguments, a target object and a message identifier:
    #
    #   anApp.addChore(anObject, aMessageId)
    #
    # A second form takes a Method instance as its single argument:
    #
    #   anApp.addChore(aMethod)
    #
    # For this form, the method should have the standard argument list
    # for a FOX message handler. That is, the method should take three
    # arguments, for the message _sender_ (an FXObject), the message _selector_,
    # and the message _data_ (if any).
    #
    # The last form takes a block:
    #
    #   anApp.addChore() { |sender, sel, data|
    #     ... handle the chore ...
    #   }
    #
    # All of these return a reference to an object that can be passed to
    # #removeChore if it is necessary to remove the chore before it fires.
    #

      tgt, sel, ptr = nil, 0, nil
      if args.length > 0
