I'm sure it fits there and the memory consumption is caused by the complicated
texturing, media, csg, unnecessary object copying or something. Posting source
could help in investigation.

Becouse it would use no less memory than spheres. You can crate one "mesh
sphere" and clone it many times as it is done internally for copied meshes
however every mesh will store pointer to original structure + transformation
while original sphere store only four floats (center + radius) for not
transformed sphere. You have to store texture and other object modifiers the
same way in both 'versions' of sphere.

I have tried clone object for large csgs and will try again it probably for
3.5 sources.
