  Modified files:
    sys/netinet          tcp_output.c 
  Log:
  When attempting to transmit a packet, if the system fails to allocate
  a mbuf, it may return without setting any timers.  If no more data is
  scheduled to be transmitted (this was a FIN) the system will sit in
  LAST_ACK state forever.
  
  Thus, when mbuf allocation fails, set the retransmit timer if neither
  the retransmit or persist timer is already pending.
