My thought is the left track should start the Turing machine, which is more of an infinite sum joke than the halting problem necessarily? Or the halting problem bit is a sort of tangential pun. The right should just be an infinite track with a person at the end.
Edit: I suppose the infinite sum/halting problem are better described as two sides of the same coin than tangential.
Data in memory will be offloaded to swap space. I doubt we'd notice any fluctuations since we're part of the simulation, but externally it could slow to a crawl and basically be useless. They might shut it down, hopefully just to refactor. But again we probably wouldn't notice any downtime, even if it's permanent.
Well, I know what my next project will be
