my machine.

I tried 2 and 3 processes I think, but with PETSc 3.1-p8. I'll upgrade
PETSc and try again.

I'm marking this as invalid. It works fine for me with mpirun -n 3 and PETSc 3.2-p5. Feel free to mark it as triaged again if it still doesn't work for you but then target it to trunk (or 1.1...).
