A trimesh has no concept of "above" and "below", unlike a plane. So if
your sphere passes completely through the mesh in one time step no
collision will be returned. There is a heightmap contrib that can
handle this case.
I'd be curious to hear if anyone has come up with a workaround for
this problem, maybe I can write it up on the wiki.
