If your program is not CPU bound, then you would be infinitely wiser to use an event loop1 or coroutines2. If you are not CPU bound, then the entire value proposition of threads does not apply to you. Ok. Give me a non-thread-based solution in Python that can parallelize IO-bound tasks as easily, universally, and naturally as throwing in 3 lines of concurrent.futures.ThreadPoolExecutor and concurrent.futures.as_completed.
