[ODE] Infinite sliding... ?

[Jon Watte (ODE)]

First, you should probably use a mu that's not infinity. Try 10.

Second, you need to make sure you use fixed time steps. All calls to 
dWorldStep() (or the faster equivalents) need to pass in the same value 
for delta-time -- no exceptions!

Third, you may want to enable auto-sleeping (disabling) of bodies at 
rest, if it isn't already.

Fourth, you probably want to add dampening forces and torques to each 
non-sleeping body for each step. There's an entry in the FAQ/Wiki about 
this, IAICR. The most important part is actually the dampening torque, 
in my experience.

Cheers,
