	I am probably one of the few people on this list who has 
actually used this book, and I still have my copy from fifteen years 
ago somewhere around the house.  I even recall trying to grok the MIX 
assembly code.  If you can provide an exact page reference, I would 
appreciate it.

	I believe that this assumes that the hash buckets are a 
consistent size relative to the overall capacity.  However, as the 
overall capacity grows by orders of magnitude, I believe that this 
generalization fails to deal with the relative logarithmic size of 
the hash buckets.
