Speed Time for one overflow
10Gbits/s => 3.436 seconds 1Gbit/s => 34.36 seconds 100Mbits/s => 343.6 seconds

For anything up to (and including) 1GBit/s it is possible to do in easily in userspace, but then were are getting into an area where a program would have to check the files every 3 seconds (and a bit of load could delay it long enough for an overflow to happen.)
