The result of such a query may be observed as nil at any point after a
weakly-pointed-to object becomes eligible for reclamation by the garbage
collector.
More specifically, weak pointers become nil as soon as the garbage collector
identifies that the object is unreachable, before it is made reachable
again by a finalizer.
In terms of the C# language, these semantics are roughly equivalent to the
