"throw it away" sure looks like it means the entire hashtable, not just its tuple contents.
I don't know if I can comment clearly to help, but from my experience, destroying and rebuilding the hashtable is a waste if possible, resetting it. By analogy, I have code with arrays where, I reuse them, with only one line, instead of reconstructing them. a->nelts = 0; / * reset array * / If possible, doing the same for hashtables would be great.
