Well, this is meant to be an implementation detail, as
different factories can do it in different ways, but
the current ones are like this: value objects are stored
in a static STL-like container (the factory core) along
with some housekeeping info (a refcounting var and
some more stuff), and what the flyweight really boils
down to is an intrusive_ptr to this value element. When
the refcount reaches zero, the element autoerases itself
from the container.
