The class MEMORY from the support library has a function `dispose'.
Whenever an object is destroyed by the garbage collector this
function is called.

To get the behaviour you desire, inherit from class MEMORY and
redefine the `dispose' function.

The function is not exported, so it does not show up in the
class interface and therefore it is not described in the library
manual.
The only place where it is documented is in the `RELEASE 2.2 OVERVIEW'.
