not true. I probably wasn't very clear on the ref counting. The
distributed ref counting (with special methods increment()/decrement()
is only used from parents to children. Children aren't considered
owner of a reference to the parent. This works since the parent would
detach itself from the child in case of destruction (though only in the
destructor - there is still some time for an upcall to fail after the
parent is deactivated and before it is destructed).

Could you please rephrase that ?
