title: Run command for all files in parallel
body: <p>I have the following command on the build-server as a part of the build process:</p>
  
  <pre><code>os.system ('signtool sign /a /t http://timestamp.verisign.com/scripts/timstamp.dll "%s\\*.exe"' % (dir) )
  </code></pre>
  
  <p>This command signs each executable file in the specified directory. Is there a way to run this command in parallel for each executable file using Python? Is there something like <a href="http://en.wikipedia.org/wiki/OpenMP" rel="nofollow">OpenMP</a> for Python?</p>
