I will check into `asyncio` and Python threads. I used multiprocessing as my first project into asynchronous programming. The previous use-case was using Python + multiprocessing to run MacOS `say` (using Python subprocess) - so I could invoke it 10-20 times simultaneously on my computer, rather than waiting for each to complete. I experimented a bit with how many concurrent processes to run (using `time` to clock how long the runs were).
