Sorry, I didn't see your email with the suggestion earlier.
To be honest I'm not sure if this comment adds much value, or if it is
even correct. The poll doesn't "succeed" or "fail". It just returns
a mask indicating if there is any data to read or if the user can write.

Isn't the commit message + 'git blame' enough to remember why it was
done this way?

Thanks,
