TL;DR

I create an asyncio.Queue with a meaningful positive maxsize, start a fixed set of owned consumers, and make producers await put(). When the queue is full, producers slow down instead of retaining unlimited work. Each consumer calls task_done() in finally for every successful get(), and the coordinator can await join() to know all accepted items reached completion handling.
