> From MESOS-2300 as well, it looks like this test is not reliable:
> {code}
> [ RUN      ] PerfTest.ROOT_SampleInit
> ../../src/tests/perf_tests.cpp:147: Failure
> Expected: (0u) < (statistics.get().cycles()), actual: 0 vs 0
> ../../src/tests/perf_tests.cpp:150: Failure
> Expected: (0.0) < (statistics.get().task_clock()),
> {code}
> It looks like this test samples PID 1, which is either {{init}} or {{systemd}}. Per a
chat with [~idownes] this should probably sample something that is guaranteed to be consuming
cycles.
