With complex CSG, try bounding differences, as well as intersections
with infinite objects (most often planes). Then specify -ur on the
command line.

You can build your own bounding tree but POV will do it better *if* it
has the bounding box info. So it's best to just bound the unboundable
and specify -ur (do not remove user bounds).
