As discussed in D108488, testing for invariants of omp_get_wtime would be more reliable than testing for duration of sleep, as return from sleep might be delayed due to system load. Alternatively/in addition, we could compare the time measured by omp_get_wtime to time measured with C++11 chrono (for portability?). Differential Revision: https://reviews.llvm.org/D112458
