Well, this goes back to the time of Egil Skalagrimsson, when communication
devices used the 8th bit for something called parity. Many of these devices
were thick-skulled and sturdy enough to survive to this day. Thus, following
the well-known network principle "be liberal in what you send and conservative
in what you receive" (or was that the other way round?), some of the more
successful networking protocols have to assume there might still be an axe
swinging somewhere between the two end systems that they don't know about.
