      ps reports vsz 28.52 GB

      mms reports
      virtual 28.52
      mapped 13.02
      non-mapped 2.47

      mongostat reports
      vsize 28.5g
      mapped 13.0g
      non-mapped 15.5g <--- believe this is wrong

      Believe that MMS has it right as there is no reason for non-mapped memory in this test to be 15.5 GB. Possibly mongostat is computing non-mapped as vsize-mapped instead of vsize-2*mapped?
