Thanks, I am well aware of every kind of multiprocessing and quasi-threading in the standard library, having built several large Python systems over the years.

Thanks, I am well aware of every kind of multiprocessing and quasi-threading in the standard library, having built several large Python systems over the years. I also understand the benefits of task queues. However, there are many cases in which you do not need any of those. Specifically, everything you wrote applies to the web backend/distributed systems usecase. Doing things in the background in a simple application, not so much. My problem is exactly with introducing distributed systems machinery for a local process on a single machine that doesn't need any of that.
