RSS is Resident Set Size, the number of in-core memory pages currently
occupied by the process. Not the process size, or even amount of used
memory for this process.
Swapping reduces RSS as pages swapped out is no longer resident in
memory.
Virtual memory allocations/reservations don't show up in RSS as those
just exists "in void".
Shared objects gets accounted for all their in-core pages, even if not
touched by this specific process or shared by a zillion other processes.
