If you delete something and attempt to use another reference to the
deleted object, the behavior's undefined.  Basically the same thing as
accessing a dangling pointer in C or C++.  'delete' is really just
there for when you *know* that there are no other references and you
want to ensure that it gets cleaned up immediately.
