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