Flaky test: test.test_capi.test_misc.Test_PyLock.test_lock_two_threads

Bug report

I noticed a spurious test failure in test_lock_two_threads when running the test suite. I'll put up a PR to fix this.

test_lock_two_threads (test.test_capi.test_misc.Test_PyLock.test_lock_two_threads) ... Assertion failed: (test_data.m.v == 3), function test_lock_two_threads, file test_lock.c, line 82.

Stack trace
