* Rename to clarify purpose of test * Simplify test info to avoid unnecessary bit-rot * Have message_ring print PNN for clearer output and update patterns in test script to suit. * Drop quantitative percentage check since this is hard to predict when under extreme load. To compensate, tighten up expectations for the total number of messages in each direction: at least 10 messages are required over 10 seconds.
