  As an after thought the reason that bounding helps is a two fold process.
First an infinite object that has a finite bounding object applied to it
becomes clipped to the size of the bounding object where they intersect.
Secondly manual bounding of a large number of objects in a csg operation
often helps speed up intersection testing.
  I know this does not solve the problem but it does explain why bounding
will help to correct for it.
