As soon as I sent this, I realized you need to save & restore velocities
as well.  There's an entire list on the ODE FAQ, under "resetting a
simulation."  Most of the stuff in that list doesn't change though.

By the way, you'll also have to worry about objects that were
created/deleted between "now" and the time you're rolling back to.
