4.0.1 (2019-04-10)

• Fixed an issue on Python 3 where an OSError:[Errno29]Illegalseekwould occur if logfile in the [supervisord] section was set toa special file like /dev/stdout that was not seekable, even iflogfile_maxbytes=0 was set to disable rotation. The issue onlyaffected the main log and not child logs. Patch by Martin Falatic.
