It takes up to a few seconds for the kernel to detect a hang (the gpu doesn't
really tell us, it simply stops doing stuff). So frame-freezing while that
happens is completely expected. And we also need to turbo-up the chip again,
which in some pathetic corner-cases also takes a while. 3.13 has some cool
tricks from Chris to help with the turboing.</pre>
