ss="bold"><strong>atomicity.cpp</strong></span> lets two threads race
            against each other modifying a shared variable, verifying that the operations
            behave atomic as appropriate. By nature, this test is necessarily stochastic,
            and the test self-calibrates to yield 99% confidence that a positive
            result indicates absence of an error. This test is very useful on uni-processor
            systems with preemption already.
