I have noticed that Chipmunk never seems to settle all the way, it  
stays jittery even when nothing should be moving.  Box2D only gets  
jittery when objects are under a lot of pressure.  Also, Box2D now  
supports a flag to enable continuous collision detection.  This can  
prevent high velocity objects from tunneling through thin objects.
