Pathlib throws "Bad file descriptor", but only with uvloop. #414
Description
Activity
Is this fixed by #408 ?
Doesn't seem to be, I just tested on 0.15.3, and I get the same results
Reacted by Gnome!Reacted by Thomas GraingerUpdate: on 16.0 I no longer get the core dump, but the 'bad file descriptor' persists. I wonder if there's something wrong with my system, is there some way to debug the system side of file descriptors?
Fyi: I don't know if this is related to that issue, but we see similar log entries of

@graingert Yes this fixes it for me. Thanks for finding the issue
@graingert I can confirm that your one-liner fixes the issue for me as well. I've been running my application for the last few days with your fix, and I haven't had any
OSError: [Errno 9] Bad file descriptorsince (I had dozens every day before).Thanks!
