Personally I think throwing fulldirhash out with the trash is the
right thing to do. We use directory hashing at FM, though I'm
tempted to think it's no longer required what with ext3's 32k
folder limit gone away now.
I can't see why a 32 bit hash isn't big enough though - it's no
less random, and it's not expensive to calculate.

I think looking multiple places is the pragmatic fix.
