Merging r4020: SIGWINCH/NOACCEPT signal is disabled now in non-daemon mode. Non-daemon mode is currently used by supervisord, daemontools and so on or during debugging. The NOACCEPT signal is only used for online upgrade which is not supported when nginx is run under supervisord, etc., so this change should not break existant setups.
