[New-bugs-announce] [issue40252] selectors.KqueueSelector should not be the default selector

[Russell Davis]

New submission from Russell Davis <russell.davis at gmail.com>:

There are at least two outstanding bugs where KqueueSelector behaves differently than the other selectors:

#40251
#25680

This breaks the abstraction of being able to rely on DefaultSelector() to provide consistent behavior. At least on macOS, PollSelector works reliably, so I propose using that instead of KqueueSelector when setting DefaultSelector. (Even if the above bugs eventually get fixed, sticking with PollSelector when possible seems more likely to avoid similar future issues.)
