Yes, exactly. Say you need to deliver a frame of audio or video every 5ms. You have a rendering thread and a display thread that communicate via FIFOs. The main thread waits in select() for the next frame to complete rendering or for the deadline to expire. That's next to impossible with HZ=100, because the best you can do is the deadline +-10ms. With HZ=1000 it's no problem.
