Hmm.

It was fun learning a bit about asyncio to implement this on the train
back from FOSDEM. What I have currently is attached, but it's not fully
ready. I explained a problem in the commit message - if the machine is
dead due to a panic, how can we execute copyup and other commands that
autopkgtest wants to run after a failure?

Cheers,
