Ah yes, I haven't used gevent for years and now associate gunicorn with wsgi. I have far easier experience with nodejs and golang when I need to do async parts on the backend (usually for websocket stuff), then use some message queue/passing system with celery or zeromq to communicate back and forth with the python backend.
