[osg-users] Remove all LOD children

[Bruno Oliveira]

I tried removing the children with m_rootNode->removeChildren(0,
m_rootNode->getNumChildren());
but this results in some memory being still allocated.

After that, I move the mouse around a bit in the clean scene, and the
memory starts being freed. However, It never gets to the initial value,
there is always some memory floating around.
