                                        It does not, of course, apply if an
	urgent flag is on the data, indicating the last byte of the packet is an
	URGENT boundry.  But, then again, ftp does not use that flag for anything.
	
Hmmm. I think you are wrong about the last.  The abort sequence on the top
of page 35 of RFC-959 specifies a Telnet IP - Synch sequence, and the Telnet
protocol spec says that this is to be sent with Urgent.  So, by implication,
a (correctly implemented) FTP does use the TCP Urgent pointer (not a flag!).
