I've been running this test on an SMP machine.  So far I haven't seen a
problem after finishing 27-th iteration, but I saw a lot of warnings in
the dmesg:
Sep 18 11:40:17 X345 kernel: Diagnostic: attempt to switch while mastering cpusync: 0xc030fe08

The hexadecimal number is consistent between warnings.

And although very occasionally, I saw the following message in dmesg
while running blogbench storm on the same machine(but I think I saw
this one on HEAD either):
Sep 18 12:16:05 X345 kernel: conflict with vnode 0xe9b4e898 ncp e_log.So
Sep 18 12:16:05 X345 kernel: Warning: inode free race avoided 1 times
