Great write up on something I depend on a lot but don't understand well. This also answers something I've always wondered about which is how Twisted and Tornado fit into the Python web framework landscape and whether I should use them. Tornado always seemed popular but slow and less intuitive than Flask/Django. And then Twisted was a far lower level library but people were still building APIs on it. Where does Eventlet fit into the picture? Is it a similar box of magic monkey patches like GEvent?
