Feature or enhancement

Since Python 3.2, pressing ctrl-c (SIGINT) interrupts threading.Lock.acquire() on POSIX platforms, including Linux and macOS. However, this does not work on Windows.

Now that threading.Lock and threading.RLock use PyMutex and _PyRecursiveMutex internally, this should be a lot easier to implement efficiently.
