test_crash is also an interesting test of QuickStep (it was
originally designed to test the stacking stability of StepFast as
well as show off its speed and relative lack of stack-blowing :))

One thing it most 'interestingly' shows (apart from showing that
QuickStep is somewhat quicker and slightly more stacking-stable
than StepFast) is that the stationary car throws a complete wobbly
at about 1-4 iterations, where its wheels jiggle off into orbit
around the car body, which slowly lifts off in a Repo Man sort of
way.  StepFast just jittered in a subdued way.

That might be helped by the new warm-start stuff -- I'm about
to test that, and the effect of re-ordering.

Thanks,
