Expected Behavior

pytest quits after successfully running the tests.

Actual Behavior

After printing 6 passed, 1 warning, pytest stalls and never returns. ctrl+c shows that a thread can't shutdown because it never gets a lock.

The single tests usually quit successfully.

Sometimes (but not during every run) also this traceback appears:
