58 weak reference, since the module automatically ensures that the finalizer
240    Return a callable finalizer object which will be called when *obj*
241    is garbage collected. Unlike an ordinary weak reference, a finalizer
245    A finalizer is considered *alive* until it is called (either explicitly
247    finalizer returns the result of evaluating ``func(*arg, **kwargs)``,
248    whereas calling a dead finalizer returns :const:`None`.
250    Exceptions raised by finalizer callbacks during garbage collection
256    When the program exits, each remaining live finalizer is called
260    A finalizer will never invoke its callback during the later part of

438 to register a callback without needing to preserve the returned finalizer
451 The finalizer can be called directly as well.  However the finalizer
464     >>> f()                     # callback not called because finalizer dead
465     >>> del obj                 # callback not called because finalizer dead
467 You can unregister a finalizer using its :meth:`~finalize.detach`
468 method.  This kills the finalizer and returns the arguments passed to
482 :const:`False`, a finalizer will be called when the program exits if it
534 A more robust alternative can be to define a finalizer which only references
550 Defined like this, our finalizer only receives a reference to the details
552 garbage collected the finalizer will still be called at exit.
566    If you create a finalizer object in a daemonic thread just as the program
567    exits then there is the possibility that the finalizer
