Review comment:
Maybe we could simplify this test by moving this logic to the inner
_Waiter.Predicate.evaluate_ method from line #529? Related _evaluate_ method is
already called every 100 millis, so we could get rid of the extra thread, its
_while_ loop and extra atomic boolean variable, whilst all relevant validations
would be concentrated at the end of the method. What do you think @sunhelly? We
can leave this as it is if you think it would be more complicated.
