Speaking of imperfections, your scheme doesn't take into account that
multiple files can (and will) have the same md5 hashes.

One wonders what measure of efficiency you're using, but frankly, I fail
to believe that there are only two ways of storing matching files as few
times as possible. Hashed pointers to a pseudo-directory system comes to
mind immediately, a scheme that's in use in at least one system.

At any rate, what problem are we trying to address?
