   I don't think it is a tunnelling problem. The thin capsule bobs up and down 
just on/below the terrain surface, and doesn't continue falling through. So 
it looks like collision detection/response is happening, but the contact 
forces are wrong somehow ?

   Could anyone else test this ? Any capsule of radius 0.03 and a length of 
0.5, should show the problem, on a heightmap terrain of 512.0x512.0.
