I've seen traffic lights in the UK fall back on flashing yellows - this was at around 2am in Edinburgh city centre, so traffic was moderate and it was mostly taxis (pubs and clubs kick out between midnight and 3am), it didn't seem to cause any problems at all. The driver commented that it actually seemed to be an improvement.
To cause a real gridlock doing this you have to assume everybody is using the same source of data, and only that one. Most traffic control systems also use mechanical detectors, car-spotting cameras and the like, you'd need to hack all of these systems to guarantee a gridlock.
