title: React create app hot reload is not always working on linux
body: <p>I created a react application using create-react-app boilerplate, which seems to be very popular, hot reload some times updates when any of the files changes and some times not, seems like there is a minimum duration or something like that, I'm using Ubuntu, node version 7.0, the script in package.json is <code>npm:'react-script start'</code> what I am missing ?</p>
