The external monitoring made possible by the /proc/net/tcphealth is interesting because the SRTT is proportional to the speed of one's network connection, and duplicate acks indicate that packets are being lost (or reordered, less likely) somewhere in the network. These are things you might want to know about a connection you are trying to communicate on - its individual latency and how often packets are being lost over it. Would a patch for 2.4.2 be helpful?
