After acquiring a shared lock on f1, the test verifies that f2 cannot acquire a lock. Once f1 is dropped, f2 is expected to acquire the lock, but this intermittently fails with WouldBlock. We have not been able to reproduce the issue in our local environment. We suspect a possible timing-related issue. We will investigate further.
