There was a problem hiding this comment.
LGTM, but maybe warn_on_full_buffer=False for set_wakeup_fd() is even better option?

set_wakeupfd() is unrelated to https://bugs.python.org/issue23846 or did I miss something? Moreover, unix_events.py is my reference (best implementation), and it doesn't use warn_on_full_buffer=False. |
