Not enough of one to actually drop such support, however. That would be an overly-elitist position for a lot of people to swallow and it would not send the right message about what sorts of people are driving things in the FreeBSD Project. The secondary effects of this would, and probably only in retrospect, cause us to see this as a very foolhardy decision on our parts. - Jordan > <<On Fri, 7 Jul 2000 21:10:38 -0700 (PDT), John Polstra <jdp@FreeBSD.org> sai d: > > > spinlocks I used the very nifty "simple, non-scalable reader-preference > > lock" which I found at > > > <http://www.cs.rochester.edu/u/scott/synchronization/pseudocode/rw.html > > > > on all CPUs except the 80386 (the specific CPU model, not the > > architecture).
