title: How run external tool before run config but not suspend execution of second run config/app?
body: <p>I have created an "External Tool" that runs a <code>tail</code> command and set it to run prior to final running of my application. But since <code>tail</code> doesn't end, it never runs my app! How can i make IntelliJ run the external tool asynchronously so it doesn't stop all the steps in the run config?</p>
