as i said before, it likely the layout was done to reduce directory
contention.  if you have a file buried eight levels deep the fileserver
doesnt need to traverse eight directories to find your file.  further,
afs doesnt know what underlying limitations your local filesystem is
going to have with respect to number of files in a directory.

usenet servers have understood this problem for sometime and the
afs solution seems similar.
