Great, I'll give it a try.

As for the delay, it actually seems reasonable. At 300 fps (OUTPLL removed), it
takes 3 ms to push an image to the card. At 50 fps (with OUTPLL), it is 20 ms
per frame, or about 8 ms extra delay per sleep.

Considering that we tell the kernel to sleep for _at least_ 5 ms, and the kernel
has a HZ of 250, it must sleep for at least two ticks, which is precisely 8 ms.
