I can think of an example of that, yes (both 3D holes and 2D holes). But I
seem to recall that the wider issue is that Polyhedron_3 can only
represent manifold objects, and there are plenty of ways to wind up with
non-manifold Nef3's.
Try computing the closure() of the interior() of your Nef. This should
eliminate any hanging geometry.
