+ * The original idea is due to George Bosworth of Digitalk, Inc.
+ *
+ * For a discussion of finalization and weakness that also reviews
+ * ephemerons, refer to:
+ * Simon Peyton Jones, Simon Marlow, Conal Elliot:
+ * Stretching the storage manager
+ * Implementation of Functional Languages, 1999
