If it's not a solid, then Constructive *Solid* Geometry should not work with it
at all.

You yourself even said earlier that, "There's nothing really strange about solid
meshes which do not form a closed surface, as long as the inside_vector is
defined properly." Have you changed your mind since then or something?

Further, you said that a non-closed solid mesh should behave just like a plane
or heightfield. This is *not* happening in this case, therefore--if one should
consider your earlier statements to be true--it must be considered a bug.
