Ugh.

If we're going to let people in by IP address, maybe we could let legacy
buildfarm members in by IP address. It doesn't seem particularly
helpful to expect each buildfarm owner to solve this problem for
themselves. I'd also note that if they could run git locally, they
wouldn't be needing cvsserver in the first place.
Also, couldn't we just set up the cvsserver on its own VM with a limited
amount of disk space, and not worry too much about any "DOS threat"?
If somebody does do this, block them and reinitialize that server.
