That's not the purpose of the copy ctor.  It exists solely so you can  
say things like this:

     void foo() {
        Connection conn(...parms...);
        ...do stuff...
        return conn;
     }

Without a dedicated copy ctor to manage certain under-the-hood  
details, this would fail.

You might look at ConnectionPool, as that centralizes creation of  
multiple connections, using a common create() method for all.
