Seems to run fine here with 4.1.18 on amd64, but doesn't seem to make much 
difference though.

I ran the tests again on the 8 core machine with and without rwatsons patch 
and this time with 6 tests for each setting and generated graphs:

thr + select smack dynamics with the patch really do look quite interesting

I'm currently running testround with rwatsons patch +  + mysqld
