I actually suspect that the confusin comes from replying to the wrong
mail.

I believe Kris Kennaway's response from alc@ in
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=473581+0
+current/freebsd-stable
was actually supposed to be a reply to
http://docs.freebsd.org/cgi/getmsg.cgi?fetch=434333+0
+current/freebsd-stable

... and actually had nothing to do with this thread.
