      While managing modules, I am offered a "restart" button, but when I click it, it logs this message:

      Feb 10, 2015 10:00:46 AM jenkins.model.Jenkins$23 run
SEVERE: Restarting VM as requested by username

      The restart process should "gracefully" close slave connections, as to not cause the "SEVERE" I/O errors.
