Open a web browser console and run this JavaScript:
`
new WebSocket("ws://localhost:8000/ws/")
`
...and observe messages coming over the websocket in the browser console.
Hard refresh the webpage (F5, or what have you), and continue this process of opening websocket connections after page load for a few minutes.
Watch as the memory space of the Daphne/runserver.py process grows (and never shrinks, even when you stop publishing new messages via the spam command).
