<p>As far as I can test the issue is in <code>imaplib2</code> line 2649:</p>
<pre><code>self.sock.shutdown(socket.SHUT_RDWR)
</code></pre>
<p>The problem does not happen when only closing the writer side using <code>SHUT_WR</code>. This means for some reason the reader side has been shutdown. I cannot see why.</p>
<p>Is there a reason shutting down both sides since the <code>finally</code> block does a <code>close()</code>?</p>
