+Subject: [PATCH] Fix ThreadingMock call_count race condition
+
+ThreadingMock._increment_mock_call() was not thread-safe.
+Multiple threads calling the mock simultaneously could lose
+increments due to race conditions on call_count and other
+attributes.
+
+Fix by overriding _increment_mock_call in ThreadingMixin
+and wrapping it with the existing _mock_calls_events_lock.
+
+Upstream-Status: Backport [https://github.com/python/cpython/pull/150176]
