In some tests we want to delay or retry an async task whose exact timing for success is indeterminable.
A few option come to mind:

1. setTimeout(task, n) where n is an arbitrary number that's empirically proven to be sufficient.
2. const interval = setInterval(() => {const ret = task(); if (ret) clearInterval(interval);}), 1)
3. do { const ret = await task()} while (ret != true)

Any other ideas or preferences?
