Cclientscript / Jquery

I want to get rid of jQuery completely in a layout. I removed it from the script Map and it is not loaded anymore. Fine. However, Yii keeps adding an script block with an empty jQuery wrapper before the closing body tag, which obviously provokes an Javascript error, since jQuery is not loaded anymore.

I removed everything from the layout, it is a plan Html 5 Skeleton even without the echo $content call.

How can I stop Yii from doing this? Any clue? Thanks in advance.
