    @issue: correct-message-pickup

    I'd bet that, because work gets put to the back of a queue, these start messages all get processed
    before any of the work they produce --- not ideal. Should change to either pick up work from the queue randomly,
    or space them after random (but sensible) number of ticks.

    (This might be a change to the Troupe, if they pick up work randomly, or a change to
    how I deploy the messages otherwise.)
