Bug description:
  [Impact]
  Restarting rsyslog causing logging from python based daemons to lockup.

  [Test Case]
  sudo apt-get install python-eventlet
  == run this script script
  #!/usr/bin/env python

  import eventlet
  from logging.handlers import SysLogHandler
  import time
  import logging

  eventlet.patcher.monkey_patch(all=False, socket=True)

  logger = logging.getLogger('log')
  logger.addHandler(SysLogHandler('/dev/log'))

  while True:
      print "send a message to logger"
      logger.error("syslog test")
      time.sleep(1)
  ==
  sudo service rsyslog stop
  sudo service rsyslog start
  ("send a message to logger" log messages will just stop)

  [Regression Potential]
  The proposed fix is in all py2.7 versions > 12.04 right now and is not causing problems.
