This is neat, but it's weird how such trivial things (in this case "a coroutine has a smaller context switching overhead than a thread, though it often is only relevant in synthetic scenarios with the tiniest quanta") now merit "a paper". Professionally delivered in PDF form with loads of citations.

I think this is a side effect of the arXiv AI-paper explosion where everyone is "publishing" "papers" on such prompt engineering magic as "delimiting my letters with spaces made it count them slightly more accurately", etc, this stunning piece of research having a dozen authors across three educational institutions and two corporations.
