   The cost of throwing exceptions will in some cases be improved because   
   you'll move the exception object instead of copying it, but once that   
   move or copy is made, the process of unwinding is similar.  Move   
   semantics may mean there are fewer non-moved-from objects to destroy   
   during unwinding, but broadly speaking I wouldn't expect that to make a   
   huge difference.
