// GetLength/GetKey/GetItem.
// Any modifications to the data in the map can cause all items to be reordered.
// Nothing is guaranteed about the order of items in the map.
// For the purpose of quota each character in the key and value strings is
// counted as two bytes, even if the actual in-memory representation of the
// string only uses one byte per character.
