+-------------------------------------------------------
+This is plumbing that DOES NOT need to be CHANGED
+-------------------------------------------------------
+Implementor's note: Python seems to very agressively
+buffer stdouot. The end result was that rsyslog does not
+receive the script's messages in a timely manner (sometimes
+even never, probably due to races). To prevent this, we
+flush stdout after we have done processing. This is especially
+important once we get to the point where the plugin does
+two-way conversations with rsyslog. Do NOT change this!
