&gt; Such a feature would be useful for certain debugging situations, but it would be disastrous to have it enabled on a production box.<p>I&#x27;ve seen that exact thing (and worse...) on a production server in some job recently. But that big all-caps warning wasn&#x27;t there, the docs were absent and there was no config bit to switch on&#x2F;off, I found the file more or less by accident (wondering what all the io was that ate up the machine).
