And I must do more work in my class by adding IUnknown to the
TMySuperClass too.
Dunno whether this is required for bare Delphi interfaces. Reference
counting does not require IUnknown, as can be seen with dynamic arrays
and strings.
Delphi's interfaces ALWAYS descend from IUnknown thus one must always
have the QueryInterface, AddRef and Release methods implemented.
