Not really. I considered some of the users to set quite a large min_size (such as 1024 buckets). The min() makes sense to me in that it's the smallest possible value. If memory later becomes available and the hashtable is resized to a more appropriate value, couldn't any issues regarding collisions not be dealt with organically? And we've agreed that allocating a tiny table is the least of our problems. Thanks, Davidlohr
