Ok, MMTests 0.06 (released a few minutes ago) patches autonumabench so
it can run the tests individually. I know start_bench.sh can run all the
tests itself but in time I'll want mmtests to collect additional stats
that can also be applied to other benchmarks consistently. The revised
results look like this

The System CPU usage is high but is compenstated for with reduced User
and Elapsed times in this particular case.
