Yeah, that's about what I'm seeing on Linux and OS X. (Though for some
weird reason I'm seeing 10x as fast on OS X when I do "python
benchmark.py /usr" -- hence my comments in the README.)

Anyway, thanks for the benchmarks, guys. I'm satisfied with the
Windows results. But I'll need to rewrite the Linux version in C (to
match os.listdir) before these results are really meaningful.
