Setting a retransmission timer on an ACK makes no sense; I don't think tcp_output will send an ACK on a retransmission timeout. Setting timers in the ENOBUFS case is at best a partial fix. If the ACK is lost locally, we know; if it is lost elsewhere, we don't. We need timers in any case. Setting a local timer for the ACK case is no better for latency than having the other end run a retransmit timer.. If there is a problem with setting the retransmit timer for a FIN, let's fix that. Otherwise, I stand by my recommendation of deleting the code to set a timer.
