    Description

      Current jcstress infrastructure is oblivious of CPU topology, and relies on luck to get the actors scheduled across/within interesting CPU packages, cores, threads. This can be done better by employing per-actor affinity, CPU topology parsing, and some combinatoric generators to cover all basic cases.
