That seems unduly restrictive, since an SVR2.0 emulation is available
(to source licensees) for 4.2/4.3BSD systems.  The added overhead is
practically unobservable, so our official portability policy has been
to target for the widest range of SV-compatible systems.

I'm curious why this is a factor.  Surely any site running 6th Edition
UNIX should have acquired a license upgrade, then the BRL/JHU version
of UNIX, 2.nBSD, or some similar modernized version?
