> There's some threaded python code of course

A fairly common pattern for me is to start a terminal UI updating thread that redraws the UI every second or so while one or more background threads do their thing. Sometimes, it’s easier to express something with threads and we do it not to make the process faster (we kind of accept it will be a bit slower).

The real enemy is state that can me mutated from more than one place. As long as you know who can change what, threads are not that scary.
