You might want to look at some of the work that Eric Dumazet has done in the networking stack with rcu hashtables that can be resized. For a trivial hash table I don't know if the abstraction is worth it. For a hash table that starts off small and grows as big as you need it the incent to use a hash table abstraction seems a lot stronger.
