You know, we wouldn't necessarily have to give up M->N restart with
this feature.  If N>M, processors M through N-1 twiddle their thumbs
until the next repartitioning (which we will eventually be able to do
with ParallelMesh, I swear), and if M>N, processor i also loads files
i+N, i+2*N, etc. until there's nothing left to load.

That would be more than 5 lines of code, but we could add those 5
lines now and then extend the capability later without changing the
API.
