django.core.servers.basehttp.FileWrapper disappears in Django 1.9
<p>I am migrating from django 1.8 to 1.9. and I got the following error:</p>

<blockquote>
  <p>ImportError: cannot import name 'FileWrapper'</p>
</blockquote>

<p>I import it as follow:</p>

<pre><code>from django.core.servers.basehttp import FileWrapper
</code></pre>

<p>Searching this name in django 1.9 release notes gives no result. What is the replacement for <code>FileWrapper</code> ?</p>
