I was given this link: http://hunger.hu/webgl.html which was supposed to crash
any video driver, and it really did a hiccup. Fortunately, after 1 second the
kernel detected GPU lockup, and reinitialized everything just fine.

As far as I can tell that javascript doesn't do anything sinister, just tries
to render 200k triangles with a single glDrawElements() call. Shouldn't there
be a protection against such simple overflows somewhere?
