The timerlat "top stop at failed action" test was relying on "ALL" being printed immediately after the "1" from the threshold action. Besides being fragile, this depends on stdbuf behavior, which is easy to miss when recreating the test outside of the framework for debugging purposes. Instead, use the expected/unexpected text mechanism from the corresponding osnoise test.
