@issue: correct-message-pickup
@description
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.)
