Hey Józef,
Initially I thought it would be required too. But talking about it with
Jason, it shouldn't be needed because both of those operations are
transfer types and that should guarantee they be ordered.
It just happens that our implementation uses 2 different bits of HW and
so we need to deal with synchronization internally.
