os: Use NotifyFd for ErrorConnMax
commit c3fea428aed919826130ef8ebdb2cceb445a845b
Author: Keith Packard <keithp@keithp.com>
Date: Tue May 24 20:51:31 2016 -0700
os: Use NotifyFd for ErrorConnMax
Instead of open-coding a single FD wait, use NotifyFd to wait for the
FD to become readable before returning the error message.
