It can work for that case, but I think that is not a good ideia.

If you are using a TInterfacedObject descendant, it will call the 
_Release when out of context, so in that especific case seems to never 
go out of context, and then you _realease call works, but in other place 
it can go out of context before, and the you will have others AV.

- As Joao suggest, the best way is create a weak reference, where when 2 
objects need to reference each other one should use Pointer to hold one 
- Avoid circular reference
- Create a Finalization method that will set one of the references to "nil"
