@tjquinno I don't think this actually retries anything since only usage always returns true and this thing doesn't catch exceptions. We do have really fancy fault tolerance Retry which works really well.

You're right. I'd intended for the retry method to repeat if the work returned false (and you are correct, so far the only use returns true) or if the work threw an exception (such as the asserts in the lambda which is passed to retry in its only use).
