Judging from _A Quarter Century of UNIX_, I slightly misrembered.
UNIX/32V was the port to the VAX, but it didn't yet include demand
paging. That feature was added only in 3BSD. That doesn't really
matter, though, for the point I was trying to bring across: Saying
"FreeBSD doesn't actually swap these days; uses demand paging" is
rather misleading because that makes it sound like a recent innovation
when it is in fact almost forty years old.
So, yes, "swap" space is a misnomer, but then again, "electricity"
today isn't really about rubbing ambers together either.
