  Previous Weak Reference Work in Python
  
!     Diane Hackborn's vref work.  'vref' objects were very similar to
!     java.lang.ref.WeakReference objects, except there was no
      equivalent to the invalidation queues.  Implementing a "weak
      dictionary" would be just as difficult as using only weak
      references (without the invalidation queue) in Java.  Information
!     on this appears to have disappeared from the Web.  Original
!     discussion occurred in the comp.lang.python newsgroup; a good
!     archive of that may turn up something more.  Dianne's old Web
!     pages at Oregon State University have disappeared.  I've sent an
!     email to what appears to be a recent email address for Dianne to
!     see if any information is still available.
