>Description:
cat /proc/<some program's PID>/statm
2nd and 3rd values are always zero.

from linux man proc:
2nd value:
resident   (2) resident set size
           (same as VmRSS in /proc/[pid]/status)
3rd value:
share      (3) shared pages (i.e., backed by a file)

For quick access, these values are set at src/sys/miscfs/procfs/procfs_linux.c:364-401.

this affects sysutils/htop.
