As an alternative one could periodically One problem with the MTU-type solutions is that the other machine in question is only 12ms away. 36 packets transmitted, 35 packets received, 2% packet loss round-trip min/avg/max/stddev = 12.418/12.798/16.146/0.732 ms ... so there's not a lot of room for several packets to be in transit. I had a look at the code mentioned, but it's beyond me (at least at my current amount of business) to modify that code.
