   * Assign a ${@link Queue.Executable} to this OneShotSlave. By design, only one Queue.Executable
   * can be assigned, then slave is shut down. This method has to be called just as the ${@link Run}
   * as been created. It run the actual launch of the executor and use Run's ${@link
   * hudson.model.BuildListener} as computer launcher listener to collect the startup log as part of
   * the build.
   *
   * <p>Delaying launch of the executor until the Run is actually started allows to fail the build
   * on launch failure, so we have a strong 1:1 relation between a Run and it's Executor.
