Any plans for a finalize-instance method?

[eero@newton.arc.nasa.gov (Eero Simoncelli)]

Are there any plans to incorporate a "finalize-instance" method
(complementing the initialize-instance method) in the CLOS spec?  This
method would be called after the instance was orphaned (i.e.  all
references destroyed), but before it was garbage-collected.
Obviously, this requires an implementation-dependent hook into the
garbage-collection process.  This would allow cleanup of allocated
foreign or system structures, static data resources, etc.
