No. They both induce unnecessary overhead and the workers don't have
scheduling and re-scheduling capabilities. The workers would have to
have something like that so the collector can just snatch the finished
results without having to do anything else.

With the current core structure, the capability to do so simply isn't
there.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
