-Fix a bug on asyncio.Queue
+Fix a bug on :class:`asyncio.Queue` to preserve the FIFO order when putting and getting items.
+Currently, it is possible to put a new item when queue is not full and there are already waiters.
+This fix will propose to check the dedicated *waiters* deques before input/output on queue.
+When putting, if the queue is not full or if the *waiters* deque is not empty, we will have to:
+
++ in the :meth:`put`, append the task to the *waiters*,
++ in the :meth:`put_nowait`, raise a new exception.
+
+The behavior of the get part should be identical.
