Andrew Stitcher commented on PROTON-2022:
-----------------------------------------
This issue is caused by the authz test closing the file handle in a signal
handler.
*This is not a legitimate thing to do*
This is also not legitimate in python 2 either. But in this case the Interrupt
signal gets through to the code in _io.py which specifically ignores SIGINTR
and the event loop does not try to run poll again with an invalid file handle.
It fails in python 3 because poll automatically retries the underlying system
call when it receives SIGINTR automatically.
