    This is the lowest-level retry helper. Generally, you'll use the

        target(Callable): The function to call and retry. This must be a
            nullary function - apply arguments with `functools.partial`.
        predicate (Callable[Exception]): A callable used to determine if an

        sleep_generator (Iterable[float]): An infinite iterator that determines
            how long to sleep between retries.
        deadline (float): How long to keep retrying the target. The last sleep

[flaky-bot]

Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (22788da), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

[tmatsuo]

I'll bump the timeout.
