I'm working on my IRTC entry and am continuously getting I-Stack overflows
although i'm already using max_intersections above 1000.  

1) Are there other things apart from intersection/difference affecting
this and what are the CSG constructions needing a high max_intersections -
intersections containing a lot of objects or highly nested CSG?

2) How does increasing max_intersections influence the rendering speed in
general, anyone any experience concerning that?
