> Is the constructor REALLY a private member, Gambit? :)

Yes, it is, actually.  One of the design features of a singleton is that
nobody outside of the class is allowed to create arbitrary instances of the
class except for itself.  If you look at the code more closely, you see that
the Instance() method is the only one creating the actual instance of the
class.  Since Instance() is a member of the class, it has access to the
private members, including the private constructor.  By making it private,
no code outside of the class can create their own instances.  That ensures
that all code outside of the class can only access the actual class instance
in a single manner, hense the name and design of a singleton class.
