There absolutely can be value. However, ODE, as currently implemented, 
doesn't quite allow you to separate collision and simulation, because of 
the dGeomMoved() call. If that could be buffered and deferred, you could 
split into at least two threads. You could even use more threads, after 
collision broad-phase is done for a step.
