The 'works off all remaining jobs before exiting' example raced the worker loop against TERM signal delivery. On slow/contended runners the drain flag (exit_on_complete) flipped late, so work_off ran extra times and the count inflated past 3. Block the worker after its first work_off call until the test confirms the drain TERM handler has set exit_on_complete, then release it. This removes the timing dependency and makes the call count deterministic.
