-Please, please tell me it's entirely different from that of sVr3.

Yes, it is.  SVR3 memory management was based on "regions" a la VMS;
SVR4's VM is a page-based system based on SunOS's approach.

I mean that BSD's fundamental networking mechanism is the "socket"
while SVR4's is based on streams.  The word "base", and especially
the mention of "r-commands", should indicate that I wasn't talking
about global protocols.  TCP/IP, UDP, etc. are supposed to be
supported in addition to the usual AT&T-specific facilities.

I'm not sure I should volunteer this information, but the title
foil for the "SVR4 Overview" from the Baltimore USENIX conference
presentation had Marilyn Partel's name on it (mar@attunix.att.com).
Perhaps she can send you the complete information packet as handed
out in Baltimore, or tell you where you can get it.
