Also, it might be temping to use /proc/self/status instead because a) it has
more memory stats and b) the fields are labeled so it is probably more
future-proof.  The extra work to parse the data would be worth it.  The big
problem with this approach is that other unix-like OSs have radically
different data in that file (e.g. Solaris has binary data corresponding to a
rather large struct.)
