Resolve `RuntimeError: Cannot install a trace function while another trace function is being installed`

Reproduce el fallo en test_nonstreaming_chat_completion[False-True-False-False] con Python 3.10 y, a continuación, inspecciona el daemon Thread-6 (_flush_loop) y la configuración de tracing mostrada en el traceback. Se considera completado cuando el test finaliza sin el RuntimeError ni la advertencia de pytest por una excepción no capturable resultante.

I keep seeing this:

__________ test_nonstreaming_chat_completion[False-True-False-False] ___________
/usr/lib/python3.10/threading.py:973: in _bootstrap
    self._bootstrap_inner()
/usr/lib/python3.10/threading.py:1011: in _bootstrap_inner
    _sys.settrace(_trace_hook)
E   RuntimeError: Cannot install a trace function while another trace function is being installed

The above exception was the direct cause of the following exception:
