Heh, I did that too, but kept it a secret. That tells me rand is a very
weak function. I think the 2^15 answer u got is a coincidence. Do it 5
times, u'll get 5 answers. It doesn't have anything to do with the hash
itself. (AFAIK) It only gets invoked upon a *duplicate*, not a unique. The
no. of keys is 967232.
