Locks:

* :class:`Lock`

* :class:`Event`

* :class:`Condition`

* :class:`Semaphore`

* :class:`BoundedSemaphore`

Queues:

* :class:`Queue`

* :class:`PriorityQueue`

* :class:`LifoQueue`

* :class:`JoinableQueue`

asyncio locks and queues API were designed to be close to classes of the

:mod:`threading` module (:class:`~threading.Lock`, :class:`~threading.Event`,

:class:`~threading.Condition`, :class:`~threading.Semaphore`,

:class:`~threading.BoundedSemaphore`) and the :mod:`queue` module

(:class:`~queue.Queue`, :class:`~queue.PriorityQueue`,

:class:`~queue.LifoQueue`), but they have no *timeout* parameter. The

:func:`asyncio.wait_for` function can be used to cancel a task after a timeout.
