   // Destruct its previous parent to free precious memory resource :)
   // and since *p belongs somewhere else, it will not be touched.

   // a thousand lines/function calls to make up our mind whether
   // we are going to destruct *p or add it to another parent.

   // destructed with tmp at the end of the code block
   // if a newdad is not successfully found.
   // this is the expected behavior
