Hmm ... I think checking /tmp/.X%d-lock isn't enough ...
On the machine where run 3 buildslave, I have only
these lock files: .X0-lock, .X90-lock .
But there are three xvfb-run.XXXXXX directories
with Xauthority files contain the following numbers: 84, 39, 90.
(These numbers were passed to xvfb-run when we started the bots.)
And there are two sockets in /tmp/.X11-unix dir: X0 and X90.
