tornado.locks – Synchronization primitives¶
New in version 4.2.
Coordinate coroutines with synchronization primitives analogous to those the standard library provides to threads.
Warning
Note that these primitives are not actually thread-safe and cannot be used in place of those from the standard library–they are meant to coordinate Tornado coroutines in a single-threaded app, not to protect shared objects in a multithreaded app.
