Performance regression in the SMP fix patch

The SMP fix patch has a performance regression. This was reported by Percona. They are very good at what they do. I get many ideas for improvements from comments by them and from Domas. The regression may be an issue for workloads with many concurrent updates. We will fix it.

  1. I think I found the problem. With the fix the smpfix is ~30% faster than unmodified Innodb.
