A pair of ptys can easily be used as a "pipe" - it has the same semantics -
whatever is written on one end can be read on another. Well, I don't know if
anyone is actually using it that way or not. The primary interest is to
understand some of the STREAMS overhead since the pty implementation calls
putq() for every message. Probably it is not of general interest to everyone.
Also, ptys are often used to simulate a human being at one end, so the actual
"being" may in reality be quite fast :-).
