Remember that if you define a class that shouldn't be copiable you can 
easily prevent it and avoid such mishaps by deriving privately from 
boost::noncopiable.  If you're in a situation where you can't use Boost 
then declare the copy constructor and copy assignment operator as 
private and don't define them.  (See items 11 and 27 of Effective C++ or 
item 53 of C++ Coding Standards.)
