 * This was a grand experiment - I would evaluate students based on the only
 * meaningful metric, amount of memory they actually used. This would make slab
 * allocators more interesting, as they could potentially be more efficient in
 * larger programs. Unfortunately, it is *exceptionally* hard to measure the
 * current memory usage of a program, and even harder to do so portably.
 *
 * The most promising approach was getrusage(2). This library call is available
 * on Mac OSX and Linux, and offers the ability to get the maximum resident set
 * size. At first blush this was promising, but unfortunately there were some
