Unfortunately, I could not observe such a VmRSS increase.
Here is the command line used to perform this test:
/opt/openmpi-1.4.2/bin/mpirun -np 256

occurring during MPI_INIT. Try doing a 1 byte MPI_GATHER to another
rank in MCW (e.g., to rank 5) and see if the VmSS goes to the same size
as MCW rank 0.
