  hmm.  the paper mentions squid, and it seems to be of a very low-risk
  factor, but it makes me wonder if this at-all fits into the FIN
  flood thing i mentioned on-list back a bit ago... ( or maybe at misc@ )

  which does only happen to me when the 3.3-current NAT/firewalling 
  gateway is doing 

rdr on $int_if from <LAN> to any port www -> lo0 port squid

  and said gateway is also running squid ( duplicated with 2.5STABLE3p1 )
  *in transparent mode*. 

  if i'm not running transparent and doing redirection, the FIN flood 
  doesn't happen...

  and, fwiw, it takes the gateway *down*, hardcore, in despite of 
  being a p3/450 with fxp NIC vs. the k6-2/500 with dc NIC.
