x11

I have some unit tests that need an X11 display so I plan to start Xvfb before running them, but to start Xvfb I will need a free display number to connect it to. My best guess is to see what's free in /tmp/.X11-unix but I'm not sure how to handle the race if many tests try to start simultaneously.

sshd must do this, does anyone know how?
