Subject: [PATCH] Seeing intermittent failures on restart of nodes due to a
 failure to start xvfb.

The issue is documented here:

https://github.com/SeleniumHQ/docker-selenium/issues/91

Looks to be an problem with the lock files preventing a restart intermittently. Adding a line here to remove the lock files on startup.
