restore environment to original state before restarting - prevents apps from forever poisoning the ENV by doing bad things (something overrides PATH/HOME etc) - allows use of Dotenv to load new ENV settings from disk (they do not override) Test: ``` puts "THIS SHOULD CHANGE #{ENV["TEST"] \|\|= rand.to_s}" ``` then restart the server 2017-04-01 14:12:54 -04:00			`ENV["RAND"] \|\|= rand.to_s`
