Here are a two arguments against:

1) The whole point of throwing an exception is that the program _can_ 
recover and not just clean up and exit.

2) If I write catch(...) in a destructor, I would be unpleasently surprised 
if it ends up throwing after all.

What use cases do you have in mind anyway?
