This comes up from time to time.  If you think about it for a moment
then it is pretty hard to define what "memory used by an object"
actually is.  The easiest (and probably not very useful definition)
is: it is the space used by the instance for storing a reference to
its class object and for storing its instance variable references.

Typically you would rather be interested in a particular part of the
object graph that is reachable from an instance - and here it becomes
difficult, because any object can have any number of references and
can be referred to any number of times.  Where then do you count the
memory?  Or do you count it multiple times? etc.

Kind regards
