Weak references are used to monitor object finalization:
`g_object_weak_ref()` adds a monitoring callback which does not hold a
reference to the object but which is invoked when the object runs its
dispose method. As such, each weak ref can be invoked more than once upon
object finalization (since dispose can run more than once during object
finalization).
`g_object_weak_unref()` can be used to remove a monitoring callback from the object.
dispose method. Weak references on the object are automatically dropped when
the instance is disposed, so there is no need to invoke `g_object_weak_unref()`
from the `GWeakNotify` callback. Remember that the object instance is not
passed to the `GWeakNotify` callback because the object has already been
disposed. Instead, the callback receives a pointer to where the object
previously was.
Weak references are also used to implement `g_object_add_weak_pointer()` and
`g_object_remove_weak_pointer()`. These functions add a weak reference to
