[petsc-dev] coordinates stored twice in snes ex12?

It looks like when ex12 clones the DM, it reuses the mesh data
structure but copies the coordinate vector.  Is there a reason it
can't reuse that storage?  Given that the PetscFEM routines accept the
same position array for dependent and auxiliary fields, does it even
make sense to have distinct coordinate arrays?
