This has been on my list, it's been a problem for a while. If this
series doesn't regress anything, I'm happy to take it. It'd be nice to
get a proper "idiomatic" asyncio Machine class, but that can wait. I
just got back from a vacation trip, please harass me in a few days if
I haven't cleared this off my to-do list.
