What Bruce is refering to is the idea that if a hash collision happens you
simply put the offending hash in the next available slot. The possible problem
is that you get a chaining. I.e. a long sequence of occupied slots. But that is
rare. I prefer using a recoding algorithm that computes a new index, the net
result is the same. The hash should be at least twice as large as the depth of
search to get good behaviour. A mean number of probes less than two. One other
idea is to create a new hash table each time a capture is made. The question is
if the extra bookkeeping will make it a win, I'd guess no.
