The hashing here doesn't seem very efficient. Is that part of
the on-disk format in some way? If so it would be great to
document that. If not it might be worth to look into better
hashing helpers from the library functions in the kernel (not needed
for inclusion, but probably worth it).

Other parts of the code got rid of the Window-Style all upper
case names, why add a new one here?
