 I guess we need a new rule in the keep-BC paper, saying that classes willing 
to stay BC shouldn't have inline destructor.

 You can destroy the private data by inheriting class 
KDockWidgetHeader::KDockWidgetHeaderPrivate from QObject and passing the 
KDockWidgetHeader instance that created it as its parent (so it will delete 
it automatically). *shrug*

 BTW, if you want, you can just use KDockWidgetHeaderPrivate instead of 
KDockWidgetHeader::KDockWidgetHeaderPrivate , if you move the forward 
declaration out of the class (lazy people ... including me :-/  ). It won't 
break BC, the 'd' member is just a pointer.
