jcstress results weirdness

[Andrew Haley]

I'm seeing this:

                      Test                          Cycles      Results
   org.openjdk.jcstress.tests.seqcst.volatiles
      L1_L1_L1_L1_L1_S1__Test                  > 10^-2147483648 PASSED
      L1_L1_L1_L1_S1_L1__Test                  > 10^-2147483648 PASSED
      L1_L1_L1_L1_S1_S1__Test                  > 10^-2147483648 PASSED
      L1_L1_L1_L1_S1__S1__Test                 > 10^7           PASSED
      L1_L1_L1_L1_S1__Test                     > 10^-2147483648 PASSED
      L1_L1_L1_S1_L1_L1__Test                  > 10^-2147483648 PASSED
      L1_L1_L1_S1_L1_S1__Test                  > 10^-2147483648 PASSED

Is this perhaps arithmetic overflows generating the results?

Thanks,
Andrew.
