``tornado.locks`` -- Synchronization primitives
===============================================
.. versionadded:: 4.2
Coordinate coroutines with synchronization primitives analogous to
those the standard library provides to threads. These classes are very
similar to those provided in the standard library's `asyncio package
<https://docs.python.org/3/library/asyncio-sync.html>`_.
.. warning::
Note that these primitives are not actually thread-safe and cannot
be used in place of those from the standard library's `threading`
module--they are meant to coordinate Tornado coroutines in a
single-threaded app, not to protect shared objects in a
multithreaded app.
