Description of problem:
The logrotate script does not notify the supervisord process so it will keep writing to rotated log files.
However, I'm not sure that it would be good to send a SIGHUP as this will restart all of the child processes.
I've filed https://github.com/Supervisor/supervisor/issues/1090 upstream for discussion as well.
