I did this Well it's strightforward. I just did the same some time ago for the buffer hash table. But I agree with Chuck that enlarging the hash size could harm the hash function distrubution (I should think about it some more though). I also think that I'll implement the cookie thing suggested by Mark since I am too much courious to see how much it will help (even if my mind is driven by RB-trees ;).
