The problem there is that something is twitching and jittering. That's a 
problem in your simulation that you need to fix. In my experience, the 
biggest source of jitter is not using a fixed time step. The second 
biggest source is not using any angular momentum dampening. The third 
biggest source is not using any linear momentum dampening.

Using a fixed timestep, adding a small counter-torque to each object, 
and a small counter-velocity to each object, each step, will typically 
make simulations settle down and auto-disable just fine.
