[ODE] is ODE multi-threaded?

ODE is not multithreaded.
If you profile your application, and it turns out that collision detection
and the solver have similar runtimes, you could try application-space
multithreading. (2 threads).
However, you would end up with a 2-stage pipeline, where the solver for
frame N uses collisions from frame N-1.
Not sure if you would encounter race-conditions though.
You would at minimum need to use two different joint-groups for contacts.
It would make an interesting experiment.
Anyone here got some profile stats lying around that can be shared?
I'm interested in the comparision between dSpaceCollide() and
