Suggestion one: bound it manually. The object won't have such a drastic effect
on the scene, though the object itself will still render slowly. Actually, a
fixed sphere_sweep object would be much appreciated...

Suggestion two: use the init_3d_spline function to concatenate spheres and
cylinders. It's less smooth and flexible but it works fine in most cases and
renders fast.
