Whats wrong is (if I'm not teribly mistaken) is best
illustrated by the "transaction" example in the GOTW:
Transaction::~Transaction() {
       if( uncaught_exception() ) {
         RollBack();
       }
     }
If the transaction is used in a destructor:
U::~U() {
       try {
         Transaction t( /*...*/ );
         // do work
       } catch( ... ) {
         // clean up
       }
     }
Got it.
Things probably would be better with
        if( uncaught_exception_level() > m_UncaughtLevel ) {
          RollBack();
        }
but there is no such function in C++. :-(
