It is my understanding that splitting a cell can result in a non-delaunay
configuration. The triangulation is then repaired by a flip or some other
operation that can affect neighboring cells of the split cell, is this not
the case?

For a CGAL::Delaunay_triangulation_3 have a look at
http://doc.cgal.org/4.7/Triangulation_3/classCGAL_1_1Delaunay__triangulation__3.html#aab0620a23ed075b5105f1f0a3d4a9f10

For a Triangulation_3, if the point is located in a Cell then only this cell
gets split in 4, and similar for when the point is located on a face, or edge.
