That would indicate that the CoreAVC folks did find in way to
efficiently decode cabac streams... Damn! I'd love to know how they
did this.

One more idea of things to benchmark: could you create 3 samples with
x264's option threads={0,2,4}?

I'd be interested to see if they managed to take advantage of
multi-sliced videos.
