code: @Override
      void createEntry(int hash, K key, V value, int bucketIndex) {
  	HashMapPro.Entry<K, V> old = table[bucketIndex];
  	Entry<K, V> e = new Entry<K, V>(hash, key, value, old);
  	table[bucketIndex] = e;
  	e.addBefore(header);
  	size++;
      }
docs: This override differs from addEntry in that it doesn't resize the table or remove the eldest
  entry.
