    messing up people currently using HAMMER on HEAD.
Just curious what the new directory hash will be. Is it "just" a 
different, improved hash-function with less collisions, or something 
completely different.

And in general (for my personal understanding of how things work),
how does hashing work together with the b-tree? There is no hash-table 
at all, I guess. What you do is to compare a 64-bit hash-key instead of 
doing a string-comparison of the file name. Is that correct?
