[PATCH v2] Improve the performance of --num-threads -d 31

["Zhou, Wenjian/周文剑"]

Hi Minfei,

Could you help me test the patch in the attachment?

I have run it a thousand times and haven't got a failure.
Previously, I can always get a failure after running hundreds of times.

But I'm not sure if it is the same problem you have met.

Thanks
Zhou
