title: Why does the pytest-threadleak fixture fail for daemon threads?
body: <p>I just added a pytest server fixture that spawns a daemon thread to use for tests over a session.</p>
  <p>However, this causes the pytest plugin pytest-threadleak to fail. Daemon threads should automatically terminate when the caller finishes.</p>
  <p>In the source <a href="https://github.com/nirs/pytest-threadleak/blob/master/test_threadleak.py" rel="nofollow noreferrer">https://github.com/nirs/pytest-threadleak/blob/master/test_threadleak.py</a> they use a daemon thread as a true positive for thread leaking?</p>
