if "renumber" is true, you ask the hash_sort() function to sort by value
and discard the previous keys, assigning new keys according to the new
order. As a result of the keys changing hash_sort() calls hash_rehash()
which assigns all of the new key/value pairs to their new bucket which is
calculated according to the new key.
