Ralf recommends "xvfb-run -a make test"

-a, --auto-servernum => Try to get a free server number, starting at 99,
or the argument to --server-num.

$ (xvfb-run sleep 10000 &) && xvfb-run sleep 10000
xvfb-run: error: Xvfb failed to start

(xvfb-run -a sleep 10000 &) && xvfb-run -a sleep 10000
# will sleep well ;-)

so probably what cause the bug report were two builds using xvfb-run at
the same time?
