I'm aware of that.  However, Blender crashes whenever I try to draw a 
Mesh that's a subset of the CSGObject rather then linked to it's own 
Object.  Oh, and I know the draw function gets called because I 
test-wrote it to draw a line (which worked). 

The problem seems to be in a display list function. . .do the display 
lists get their mesh data from ob->data?  In that case, it could be that 
the presence of a CSG block may be confusing it. . .
