Very interesting. I need to stand-up this program and two others
in one week, so it looks like dpq2 and message passing is the
good short term solution to reduce implementation effort. But I
would like to return to your idea in a couple months so that I
can try a fiber based implementation instead.

It sounds like you might have a rigorous way of defining and
keeping track of your state machines. I could probably learn
quite a bit from reading your source code, or the source for
similarly implemented programs. Are there examples you would
