[ODE] RE: Ragdoll sample with multiple solvers

[Dominique Louis]

Is it just me, or do some these guys writhe around in pain for a while 
at the bottom of the stairs?

I also noticed one guy getting stuck on the stairs then a little while 
latter off the stairs.

What causes these artifacts. Is it the low number of iterations or the 
number of contacts
