I presume MS Windows still doesn't provide timers with <1ms resolution, be
it event-based or something like usleep/nanosleep? I haven't seen your
original post, but I've already struggled myself to get reliable 1kHz
realtime behaviour without external hardware. I ended up with a busy-wait
loop, (hogging the CPU was acceptable in my case).
