It is used for capacity planning and scalability analysis. OSes usually show you virtual memory and resident memory, shown as the "VIRT" and "RES" columns in top. My tool does this using /proc/PID/clear_refs and the Referenced value from /proc/PID/smaps, which were added in 2007 by David Rientjes (thanks).
