Adding "no_shadow" to the union of spheres makes the rendering times
approximately equal (with distant or nearby light sources).  Thanks!

I'm guessing that the subtle change in position of the light source (notice
the distant one wasn't directly overhead) lead to lots of small shadows
being cast on other reflective objects, which in turn lead to lots of
recursion.

I haven't tried 'no_image', since this solves my rendering problem.  I don't
really want to make my objects invisible (!), so what do you expect from
this option?

Thanks again for your help!
