How to disable print "Loading configuration... done." in Sumo/Traci

Question

I'm using traci, and everytime I call traci.start it prints "Loading configuration... done.". Its really annoying because I am connecting to a lot at once and overtime. I can't seem to find where this print originates. And attempting to disable prints on this traci.start call using something such as in this question does not work. I think because a sumo server is created which is connected to and this print comes from the code for this server.

If you want to discard the complete stdout you can do the following:

import subprocess
import sumolib
import traci

PORT = sumolib.miscutils.getFreeSocketPort()
sumoProc = subprocess.Popen(["sumo", "-c", "sumo.sumocfg", "--remote-port", str(PORT)],
                            stdout=open(os.devnull, "w"))
traci.init(PORT)

This won't work with libsumo though.
