DIST code is still very much work in progress.  There will be several  
inefficiencies, and yes caching the results of locate calls where  
possible is something to look into.  One thing that may prevent it  
being viable though (haven't thought about this too much yet) is that  
you may have to cache for every valid hashcode (range of  
Integer.MIN_VALUE to Integer.MAX_VALUE), and also this cache would be  
useless/need to be flushed every time there is a re-hash.  So there  
would be tradeoffs to consider...

Keep the questions coming though!  :)

Cheers
