Thanks, that works well. I'm on an older kernel (2.6.18), so I only
have 42 entries in /proc/pid/stat, but VSZ is still in position 23.
Looking at the proc man page also shows /proc/[pid]/statm, which
collects some of the memory information, but requires me to know what
the page size is to make sense of it.
