This is referencing issue https://github.com/facebookincubator/create-react-app/issues/1753 - where react-scripts start wasn't closing upon stdin "end". I simply added one more condition on top of https://github.com/facebookincubator/create-react-app/pull/2246 that would handle the "end" case and kill the process.
I am integrating CRA with an elixir-phoenix app and when using react-scripts start from within another process, it wasn't getting closed out when killing the main process. This made it difficult having to lsof -i $PORT and kill <pid> every time I had to restart the server.
