The name_t pool is indexed by hash. It is done to avoid the cost of rehashing when the map grows (?) and the cost of hashing when looking up static values (pre-hashed).
Given that we will only rehash with a closed_hash map log(n) times, a better option is to allow a precalculated hash to be used for find and insert, and not worry about the cost of a rehash.
