=Bring in  dirhash, a  simple hash-based  lookup optimisation  for large
=directories.  When  enabled  via "options  UFS_DIRHASH",  in-core  hash
=arrays are maintained for large  directories. These allow all directory
=operations  to take  place  quickly instead  of  requiring long  linear
=searches. For now anyway, dirhash is not enabled by default.

Cool! My ~/Mail has 2420 files in it and browsing is damn slow.

BTW, this reminds me, once again, of the wonderful things like:

	http://www.cs.columbia.edu/~ezk/research/usenetfs/
	http://www.cs.columbia.edu/~ezk/research/cryptfs/

and more at http://www.cs.columbia.edu/~ezk/research/

Some parts mention FreeBSD ports  explicitly, albeit 3.0... Anyone cares
to bring this in?
