-/**
- * Little helper class to clean up static objects that are
- * held as pointer.
- * When the library is unloaded, or the app terminated, all static deleters
- * are destroyed, which in turn destroys those static objects properly.
- * There are some rules which you should accept in the KStaticDeleter managed
- * class:
- * @li Don't rely on the global reference variable in the destructor of the
- * object, it will be '0' at destruction time.
- * @li Don't rely on other KStaticDeleter managed objects in the destructor
- * of the object, because it may be destroyed before your destructor get called.
- * This one can be tricky, because you might not know that you actually use a
- * KStaticDeleter managed class. So try to keep your destructor simple.
- *
- * A typical use is
- * \code
- * static KStaticDeleter<MyClass> sd;
- *
- * MyClass &MyClass::self() {
- * if (!_self) { sd.setObject(_self, new MyClass()); }
- * return *_self;
- * }
