I think I have figured out why it behaves this way. The two
faces in the -z/+z directions are overlapping even though
they are on the outside. Therefore they are coincident
surfaces and cancel each other out. I tried this code on
my install of v2.2 and it acted the same way so it's been
around for years. I guess the way to get around it would
be to under/over scale one of the boxes so the surfaces
don't coinside but I don't like the fact you can't create an
object with this simple cgs functioin without having a little
step on the surface. Come to think of it how would you
get a clean unstepped surface while eliminating the interior
surfaces any other way ? It's a Bug ! It's a BUG !

BUMMER !
