In case anyone else's interested, the patch attached makes supervisor
send child's stdout to syslog, if stdout_logfile is set to "syslog" in
the config.
However, there's another issue that prevents me from using supervisor:
when a process is stopped using
"supervisorctl stop" command, the last lines logged by the process are
lost. I think it's the same issue as reported here:
