/*
 * A general purpose vector
 * Uses locks, so only moderately fast
 * If you need to deal with sparse data, really sparse data,
 * use a hash table. This assumes that packed data is a good idea.
 * Does the fairly trivial realloc thing for extension,
 * so 
 * And you can keep adding cool things to it
