In that case emulate (or better yet, use GNU/Linux! ;) the behavior
of the slocate(1) and updatedb(1) tools on GNU/Linux. The
updatedb(1) tool just stores all paths available on your system... like

  Find.find('/') do |path| puts path end

into a text file. Then slocate(1) simply grep(1)s for your query in
that text file. This approach is *much* faster because you
pre-compute all the paths on your system.

Imagine how slow Google would be if they searched the entire WWW
instead of searching through a pre-computed index of the WWW!
