How could that ever happen?

  def notify_observers(*arg)
    if defined? @observer_state and @observer_state
      if defined? @observer_peers
        for i in @observer_peers.dup
          i.update(*arg)
        end
      end
      @observer_state = false
    end
  end

@observer_peers will contain objects that implement the update method.
