Use spinlock instead of mutex for Threads and SplitPoint It is reported to be defenitly faster with increasing number of threads, we go from a +3.5% with 4 threads to a +15% with 16 threads. The only drawback is that now when testing with more threads than physical available cores, the speed slows down to a crawl. This is expected and was similar at what we had setting the old sleepingThreads to false. No functional change.
