Yeah, when I say nothing it means I'm happy. All this is perfect 
usage of pointers. One question I have in mind is if many bodies 
with the same material pointer would slow down the parallel runs,
but whatever the answer we can use per-body props, so everything 
is ok.

I still don't understand the point of shared InteractionPhysics. 
So many efforts just to avoid duplicating values of the friction?! 
Come on guys, just give up. (and what about parallel access to props,
which will be a lot more frequent than access to bodies props?)
