This currently has no users, but the use case is so common that I think we must support it. Note that without the appended we cannot safely remove a set of elements; a 2-step approach (i.e. qht_iter first, keep track of the to-be-deleted elements, and then a bunch of qht_remove calls) would be racy, since between the iteration and the removals other threads might insert additional elements.
