I think the test in this patch is quite similar to what Noah has
pointed in the nearby thread [1] to be failing at some intervals. Can
you also please once verify the same and if we can expect similar
failures here then we might want to consider dropping the test in this
patch for now? We can always come back to it once we find a good
solution to make it pass consistently.
