Now I have been able to grab a whole session. This is only the last lines,
the whole log is over 200 kbytes...
After this the socket state turned into CLOSE_WAIT, with the socket timers
turned off, and the sending process (sendmail) was never notified. If a
SIGIO is send manually to the sendmail process, it would terminate and the
socket would go to LAST_ACK and stay there `forever'.
