title: Python logging with Supervisor
body: <p>I'm currently using supervisor to monit and daemonize some python scripts easily. However, it seems that supervisor won't log properly. 
  The scripts I'm executing is as simple as this :</p>
  
  <pre><code>#!/usr/bin/env python
  import pushybullet as pb
  import sys, time, logging
  
  # INIT LOGGING
  logging.basicConfig(format='%(asctime)s @%(name)s [%(levelname)s]:    %(message)s', level = logging.DEBUG)
  
  if __name__ == '__main__':
      try:
              logging.info('Custom service started')
              while True:
                      #here for the sake of example, actually doing real stuff here
                      time.sleep(2)
      finally:
              logging.info('Custom service stopped')
  </code></pre>
  
  <p>And here is the corresponding conf file : </p>
  
  <pre><code>[program:myscript]
  directory=/home/pi/Documents/Scripts_py
  command=python -u myscript.py
  autostart=true
  autorestart=true
  </code></pre>
  
  <p>So I've tested many things based on many researched on google.
  Replacing logging lines by print and then flushing stdout indeeds works; same with -u option to launche the script. But print is not adequate for my needs, Python's logging module is. So I tried to flush after each logging line, and to launch the script in unbuffered mod, but nothing appears! </p>
  
  <p>Thanks in advance for any help! </p>
