+       If a segment is received with RST set and the segment is completely to  
+       the left of the receive window, ignore it.  Add some additional 
+       comments to the code that deals with received segemnts that are 
+       completely to the right of the receive window.  If an invalid SYN is 
+       received, force an ACK and drop it; if the other side really sent the 
+       SYN; it'll respond with a reset.
+       Respond to RST by ACK, as suggested in NISCC recommendation.
+       Rate-limit ACKs against RSTs and SYNs. 
+       If SYN is coming and RCV.NXT == SEG.SEQ, then ACK with value - 1.
