73        @remarks
74        Why do we do this? Well, it's because the Singleton
75        implementation is in a .h file, which means it gets compiled
76        into anybody who includes it. This is needed for the
77        Singleton template to work, but we actually only want it
78        compiled into the implementation of the class based on the
79        Singleton, not all of them. If we don't change this, we get
80        link errors when trying to use the Singleton-based class from
81        an outside dll.
82        @par
83        This method just delegates to the template version anyway,
84        but the implementation stays in this single compilation unit,
85        preventing link errors.
