 ? If you read all what I wrote, it was only for ICMP administrative
 unreachables, that is someone put a filter in the path denying the
 traffic.
 
 Other unreachables will only kill sessions in SYN-SENT state, that is
 new sessions not setup yet.
 
 The above was what was agree'd upon when it was discussed at -hackers
 earlier.
