Actually, this is pretty much what I would expect, after some
thought.  The LSLR method makes a local linearity assumption (first
order) which gets plugged into the divergence discretization (plus
one order, according to my hunch). In my experience, this gives a
second-order method.

The problem, of course, is that the local linearity assumption it
makes is reasonable with constant D, but wrong with variable D. The
question is how bad the assumption will be on variable D problems.
