I've never worked much on explicitly multi-threaded code, but in 15+ years this is a pattern I had not seem up to today. The original writer of this Thread, Nikita, also does not seem to have found `asyncio.sleep(0)` in less than 10 minutes looking for what he needed. It allows for "explcit is better than implicit", and really asserts the intention of the code writer, and have a low cost to implement in the stdlib. And it is semantically more correct at the cost of maybe 3loc on the stdlib.
