I tend to do a lot of gettimeofday()s in my code, so I was worried about
their cost and profiled. It turned out to be quite insignificant.
Not to say that it always is, though --- it can still be useful for
measuring performance of very short code snippets which are hard to
get accurate readings for otherwise.
