   probe now checks a series of consecutive, adjacent key/hash pairs before
   continuing to make random probes through the hash table.  This exploits
   cache locality to make collision resolution less expensive.

   The collision resolution scheme can be described as a hybrid of linear
   probing and open addressing.  The number of additional linear probes
   defaults to nine.  This can be changed at compile-time by defining
