* Hashing.
*
* The server uses a chained hash table to provide quick and efficient
* hash table maintenance (providing the hash function works evenly over
* the input range). The hash table is thus not susceptible to problems
* of filling all the buckets or the need to rehash.
* It is expected that the hash table would look something like this
* during use:
* +-----+ +-----+ +-----+ +-----+
* ---| 224 |----| 225 |----| 226 |---| 227 |---
* +-----+ +-----+ +-----+ +-----+
* | | |
* +-----+ +-----+ +-----+
* | A | | C | | D |
* +-----+ +-----+ +-----+
* |
* +-----+
* | B |
* +-----+
*
* A - GOPbot, B - chang, C - hanuaway, D - *.mu.OZ.AU
*
* The order shown above is just one instant of the server.
*
*
* The hash functions currently used are based Fowler/Noll/Vo hashes
* which work amazingly well and have a extremely low collision rate
* For more info see http://www.isthe.com/chongo/tech/comp/fnv/index.html
