      <span class="bold"><strong>ordering.cpp</strong></span> lets two threads race against
            each other accessing multiple shared variables, verifying that the operations
            exhibit the expected ordering behavior. By nature, this test is necessarily
            stochastic, and the test attempts to self-calibrate to yield 99% confidence
            that a positive result indicates absence of an error. This only works
            on true multi-processor (or multi-core) systems. It does not
