Yes, I do. So do you suggest using RES as a better indicator of memory 
footprint?
The program in question processes large 3D images via vtk, and I'd like 
to measure its memory usgae with different parameter configurations as 
the maximum amount of memory acquired during execution. Since SIZE often 
happens to be larger than RES, and increase more during execution, I 
thought of using it as an indicator of memory footprint.
