there is a bug in the MPI version of the PML routines #661

EXAMPLES/BENCHIE_water_PVC (which people can run using "run_this_example.sh") does not give the same result when it is run on one processor (serial mode) or on 4 processors (MPI mode), its PMLs blow up quickly when MPI is on, while they do not when PML is off. Thus there is a bug somewhere in the MPI version of the PML routines. @xiezhinan @vmont @bottero @pcristini
