    iolist_to_binary/1, list_to_bitstring/1, binary:list_to_bin/1
  • hipe: Handle Maps instructions get_map_elements, put_map_assoc,
    put_map_exact in the HiPE native code compiler.
  • mnesia: The time for inserting locks for a transaction with large
    number of locks is reduced significantly.
