It's not about the design of the PETSc wrappers, it's about getting
the things we need to initialize a PETSc MPIAIJ matrix efficiently so
we can get speedup for the parallel assembly.

The current status is that it seems to work, but we don't see any
speedup, presumably since we don't initialize the data efficiently.

What's the status of pDofMap?
