Comment 103 for bug 31037

I just noticed that the problem does not subsists if Vino/Desktop Sharing is not started with the option "Automatically configure UPnP router to open and forward ports" selected.
But if it started with this on, than de-selecting it does not bring the CPU usage down... Vino need to be "killed" 'cause too drunk... the process needs to be shut down and restarted; un-ticking the "Allow other users to view your desktop" and ticking it again has the same cycling effect.
