title: asyncio and coroutines vs task queues
body: <p>I've been reading about asyncio module in python 3, and more broadly about coroutines in python, and I can't get what makes asyncio such a great tool.</p>
  <p>I have the feeling that all you can do with coroutines, you can do better by using task queues based on the multiprocessing module (celery for example).</p>
  <p>Are there use cases where coroutines are better than task queues?</p>
