OpenCV pthreads-based implementation changes: - rework worker threads pool, allow to execute job by the main thread too - rework synchronization scheme (wait for job completion, threads 'pong' answer is not required) - allow "active wait" (spin) by worker threads and by the main thread - use _mm_pause() during active wait (support for Hyper-Threading technology) - use sched_yield() to avoid preemption of still working other workers - don't use getTickCount() - optional builtin thread pool profiler (disabled by compilation flag)
