I'm not quite sure about what kind of references to an object determine 
its "alive" quality and its readiness for garbage collection. For the 
moment I understand that *any* living reference, including non-explict 
of member classes, keep the object alive.

Would you agree that the follwoing class "NeverRelease" entails 
instances which will never get prone to garbage collection?

class NeverRelease
{
    Child1    child;

    public NeverRelease ()
    {
       child = new Child1();
    }

    private class Child1
    {
    }
}

While would you also agree that instances of the following class 
"AlwaysRelease" always become garbage because the member class is static 
and hence does not take reference to the enclosing class?

class AlwaysRelease
{
    Child2    child;

    public AlwaysRelease ()
    {
       child = new Child2();
    }

    private static class Child2
    {
    }
}
