title: Using RotatingFileHandler to log from multiple processes
body: <p>I am using the multiprocessing module to split many I/O jobs across different processes and I encountered the problem of logging from the different processes to the same log file.
  After looking for a solution I changed the file set in the logger from a normal FileHandler to a RotatingFileHandler.
  During my experiments (in the dev envr.) it worked perfectly and solved the problem, but I'm not sure it is a reliable approach.
  Is there any downside? Something I should be aware of?</p>
