"Why isn't cvsup.freebsd.org a round robin DNS entry?"

If this question is asked one more time, I'm going to go bonkers with
an axe at some user group meeting.

As a Google search doesn't give much of a definitive answer from any
of the CVSup gurus, because it's drowning in the number of people
asking this question, basing this on my own knowledge. Feel free to
expand this.
