On an amusing side note: I once was very happy that I happened to be
running ext3 at work. I accidentally started `rm -rf ~/*` and after more
than a minute I wondered why my disk was so busy ...

Anyway, thanks to its slow speed, rm only had time to eat away my rather
unimportant "archive" and "bin" directories and hasn't reached "doc"
yet. Thankfully bash sorts its glob expansions alphabetically. :D
