I'm always reluctant to add sleeps into the code (even if it is a nicely
implemented one that limits the length of the sleep).
I prefer the `backOffTo` rather than the `every`, e.g.
`.backOffTo(Duration.millis(20))`.
I'm ok with merging this because it improves the race. But the race still
exists, and may well still bite us on apache jenkins where the machines are low
powered so things could take more than 200ms.
