Concurrent Queue Patterns in Python

Concepts: pyAsyncioQueue, pyThreadingQueue, pyMultiprocQueue, pyProducerConsumer

Python has three distinct queue classes for three distinct concurrency models: asyncio.Queue for async coroutines, queue.Queue for threading, and multiprocessing.Queue for multiprocessing. Using the wrong one is a subtle bug that can cause deadlocks or complete failure. The choice depends on whether your bottleneck is I/O bound (async or threads) or CPU bound (multiprocessing), and whether you are using coroutines or OS threads.
