Comment(by rbeezer):

 Thanks, Jeroen.  Sorry for the delay in getting back to this one.

 Yes, this uses !SciPy, which in turn will use ATLAS.  It seems a
 2-dimensional eigenspace is being returned with different basis vectors.

 This is mostly a documentation patch, so I think it would be best to make
 the tests more functional - checking that returned matrices have the
 desired properties - and less about the actual entries of the matrices.
 I'll put that on my list.

 Rob
