           Break ties between two jobs, A and B, with equal deadlines by using a
           uniform hash; i.e.: hash(A.pid, A.job_num) < hash(B.pid, B.job_num). Job
           A has ~50% of winning a given tie-break.

+          NOTES:
+            * This method doesn't work very well if a tied job has a low-valued
+                  hash while the jobs it ties with do not make progress (that is,
+                  they don't increment to new job numbers). The job with a low-valued
+                  hash job will lose most tie-breaks. This is usually not a problem
+                  unless you are doing something funky in Litmus (ex. worker threads
+                  that do not increment job numbers).
