Oh yeah, one other thing to note: the test cases don't actually regression-test performance numbers, since they will vary randomly; the numbers are simply printed into the test log. It's not even clear that we can test that "fast" tracepoints are faster than regular tracepoints, since a target is not even required to implement them with different mechanisms.
