- * This test reports the overhead of sem_post to sem_wake. A circle of

- * BM_semaphore_sem_post_sem_wait - BM_semaphore_sem_post - BM_time_clock_gettime
- *
- * Differences will result if there are more threads than active processors,
- * there will be delay induced when scheduling the processes. This cost is
- * measured by trying different values of num_semaphore. The governor selected
- * will have a major impact on the results for a large number of threads.
- *
- * To reduce the chances for threads racing ahead and not triggering the
- * futex, for example the background threads finish their job before the
- * sem_wait is hit in the main thread, the background threads will run at
- * batch priority and the main thread at fifo priority. This should generally
- * guarantee the main thread completes its task of priming itself with the
- * sem_wait before the other threads can start. In practice without the
- * sched mechanics here, this works on Android configured kernels, this is
