This is the first bug that I file, so please bear with me here. I was advised to file this after running into a strange situation with asyncio 3.4.3. Adding signal handlers for any other signal but SIGINT throws strange exceptions. The attached source code produces the following traceback: Exception ignored in: <bound method BaseEventLoop.__del__ of <_UnixSelectorEventLoop running=False closed=True debug=False>> Traceback (most recent call last): File "/usr/lib/python3.5/asyncio/base_events.py", line 501, in __del__ File "/usr/lib/python3.5/asyncio/unix_events.py", line 58, in close File "/usr/lib/python3.5/asyncio/unix_events.py", line 139, in remove_signal_handler File "/usr/lib/python3.5/signal.py", line 47, in signal TypeError: signal handler must be signal.SIG_IGN, signal.SIG_DFL, or a callable object I asked in #python on freenode and was asked to file this bug. Thank you for your consideration |

Hm... We've seen this exact same crash reported several times before, and it was closed without a fix AFAICT each time. - https://github.com/python/asyncio/issues/396 - http://bugs.python.org/issue23548 IIUC the conclusion in the latter was that this is due to a bug in the user code (forgetting to close() the event loop). |

I think I have a patch for this here: https://github.com/python/asyncio/pull/456 |
