Except when they don't. Apart from cases like short strings and small
integers where Python itself doesn't create objects more than once, you
can always implement classes that define __new__ or use metaclasses in
such a way that you cannot be sure that (or whether) calling them under
given circumstances will create new objects.

To be honest, I just don't see why this whole singleton business shouldn't
be orthogonal to the concepts of the component architecture.
