+/** Cleanup code of the full object.

+ *  The destructed callbacks might need to have a fully
+ *  created `Cpu` instance so they cannot be called `~Cpu()`
+ *  (at this point the fields of the parents have been destroyed
+ *  and the virtual methods are the ones of `Cpu`). If a `Cpu`
+ *  subclass overrides any virtual method, it should call this
+ *  method at the beginning of the destructor in order to trigger
+ *  the callbacks in the real state of the Cpu.
+ *
+ *  Once the method has been called once, it becomes a noop ensuring
+ *  that the callbacks are not for each class of the hierarchy.
+ *
+ *  A better solution would be to call a `Cpu::destroy()` method
+ *  before calling the destructor and trigger the callbacks here.
