A round trip is a security hole?   Is every packet I send 1/80th of an 
attack?   If so, if I send 80 packets without RH0, then that is equally bad!

The issue here is that the network making a judgement about what packets 
should and should not be delivered as requested requires that the 
network be omniscient.   If it were, it might as well figure out which 
packets I will send, send them, and then I need not bother to write the 
code to send them in the first place!

Do time-sharing systems refuse to run code that implements sorting using 
a bubble sort?
