This is probably the right thing to do in any case.  There are a lot
of practical problems with implementing real COM singletons.  This is
covered in gory detail in "Effective COM" topic 4: "Beware the COM
singleton".  Your approach is essentially what they recommend (modulo
programming langauge :-)).
