Hi there.  
I currently work on a ragdoll (with Verlent Integral, like described in the Jakobsen paper). It works quite nice, but I encountered a nasty problem:

If the speed of the nodes (the joints) is to fast, the clash into each other (as the bones and constraints are all flexible) and produce NaNs. I debugged a lot, but I couldn’t nail down the source of the problem.

I _think_ the relaxBounds somehow messes up, but I can’t find out why.

Hope you can help me.

(To test out the bug: drag the RagDoll around fast into one corner)
