title: CloudFormation is very slow
body: <p>I have a stack with:</p>
  
  <ul>
  <li>API Gateway</li>
  <li>Lambda</li>
  <li>Kinesis</li>
  </ul>
  
  <p>When deleting this CloudFormation stack from the AWS console, the process is very slow.</p>
  
  <p>Everything works fine until you execute the exclusion of 'AWS :: Lambda :: Function' -> 'CloudFormation is waiting for NetworkInterfaces associated with the Lambda Function to be cleaned up.'</p>
  
  <p>The time in this process takes about 30 minutes.</p>
  
  <p>Has anyone had the same problem?</p>
