[Users] output problems

This may happen if two jobs write to the same file at the same time. Did
you have an old process from a previous run still writing output when you
started a new job with the same output directory? Or is there an error in
your job startup, so that both MPI processes think they are rank 0? (Look
at Carpet's output; it will tell you how many ranks MPI thinks there are.)
