>From an OSX laptop with -S, -c 1 and -M prepared (9 runs, removed the
three best and three worst):
- HEAD: 9356/9343/9369
- HEAD + patch: 9433/9413/9461.071168

improvement here as well. Looking at the progress report, per-second
TPS gets easier more frequently into 9500~9600 TPS with the patch. So
at least I am seeing something.
