I would like to reinforce that; this module will be effectively unusable
with a normal filesystem for any significantly large database. The "value"
files will be rounded up to the nearest blocksize, wasting absolutely epic
amounts of disk space, and a standard UNIX filesystem will run out of inodes
pretty quickly.

On the other hand, reiserfs (see http://www.idiom.com/~beverly/reiserfs.html
to get an idea; find a more recent mirror if you actually intend to use it)
is rockingly good for this sort of thing. So good, in fact, that it renders
the hashdepth feature redundant. I'm hoping it will go into the standard
Linux kernel soon.
