Do you mean by the GC?

Well, it can be a bad thing if the GC most of the time run 
destructors if you do transactions that complete in destructors 
or have buffers that are flushed and closed in destructors. For 
correctness it is actually better that the GC never run 
destructors. Or... that the language is adjusted so that you get 
precise guarantees.
