Subject2.1.79: debugging messages from net/ipv4/tcp_timer.c and net/ipv4/af_inet.c
I'm using IPv4 over Ethernet (PCI NE2000 clone).  Another Linux system
doing IP masquerading is acting as the gateway. I run a caching named,
and was using Lynx, PINE, and sendmail. Otherwise, the network was
quiescent. I noticed these messages. The "Socket destroy delayed"
messages seemed to appear when the gateway's PPP link was down. I didn't
see any pattern to the appearance of the xmit_timer messages. They seemed
to show up when I wasn't doing anything in particular.
