title: spawning process from python
body: <p>im spawning a script that runs for a long time from a web app like this:</p>
  
  <pre><code>os.spawnle(os.P_NOWAIT, "../bin/producenotify.py", "producenotify.py", "xx",os.environ)
  </code></pre>
  
  <p>the script is spawned successfully and it runs, but till it gets over i am not able to free the port that is used by the web app, or in other words i am not able to restart the web app. how do i spawn off a process and make it completely independent of the web app?</p>
  
  <p>this is on linux os.</p>
