I'm testing the patch right now and everything is very happy, especially
me :) I'm running udpsic, tcpsicp and icmp, all att the same time here and
everything just works as I want it to.

Rusty, any chanse that we can increase the UDP timeout from 60*HZ to
120*HZ or maybe even 180*HZ ?

My lixq timesout with 60, I'm running with 180 right now and everything
works fine

Thanks!
