I am using flask because you know, long string of development with flask over the years, your application is growing and then you hit some walls. I do not want to rewrite everything just for a couple of views within my application.

Flask with gunicorn has its own even loop and asyncio io another one and at the end it is hard to be sure if something is working because I am lucky or because it is the way to do things.

Anyway, thank you for your example, it is really clear and easy to understand! Maybe we need a flask like framework which is asyncio based. Which mean I will need to upgrade the code to Python 3 :)
