title: Leiningen - how to kill the child process?
body: <p>When I launch a webapp with <code>lein run</code> or <code>lein ring server</code>, I get two processes: Leiningen itself, and my app. When I terminate the session with Ctrl+C, it terminates Leiningen and leaves my app running.</p>
  
  <p>How can I terminate both processes or prevent Leiningen from spawning a process?</p>
