I've seen thread::sleep wrecking havoc in async servers. There's already an issue for clippy, but the std docs could warn against it too.

LGTM, approving. You might also consider adding an additional suggestion to check the async runtime for a timer-based sleep function that allows other asynchronous tasks to run.

Warn against thread::sleep in async fn

I've seen `thread::sleep` wrecking havoc in async servers. There's already an [issue for clippy](rust-lang/rust-clippy#4377), but the std docs could warn against it too.
