Exception handling is by definition exceptional, and thus its efficiency 
is rarely important.  What is important is that it should be correct, and 
ideally clearly correct, so that someone can check its correctness easily.  
Optimizations, if they have any effect at all, typically make the 
correctness less obvious.
