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
