   Robustness, especially under program modifications. If you have such a   
   resource acquisition in just one place, that's probably ok, but then   
   you must be careful when working on the sources whether you move   
   anything into the function, namely within or outside of the catch, in   
   specific if you need to allocate another resource later.   
      
   If you need the same or similar resources in several places, it is   
   rather error-prone to write the same try-catch clause whenever you   
   need this resource. Instead, just use this administration class that   
   keeps the resource, and you don't need to worry anymore if exceptions   
   propagate out of the function.
