[issue30414] multiprocesing.Queue silently ignore messages after exc in _feeder

[Thomas Moreau]

Thomas Moreau added the comment:

I think this is a good solution as it let the user define easily the behavior it needs in other situation too. I would recommend adding the object responsible for the failure to the _on_queue_thread_error callback. This would simplify the error handling.
