This is not as strong a guarantee as it might seem. The write that makes
the object finalizable might have been done presciently before an
arbitrarily large number of other writes that appear before it in program
order. So all you're really sure of in the finalizer is that there are no
unobserved writes to the object. As Hans has observed, this isn't that useful.
