The bounding of some objects, differences and intersections for example, 
is not perfect. If you have a complex CSG(I would consider 8000 objects 
"complex"), manual bounding is often a good idea.
Also, with some arrangements of large numbers of objects, you can make a 
heirarchial bounding "tree" by using nested unions of objects, this can 
eliminate a lot of bounding box testing. Someone else might have more 
details on this...
