(In case anyone else is following this thread)

Please note that your use of the term 'weak pointer' is nonstandard.
'Weak pointers' are used in tracing/coping GC's to refer to pointers
which aren't traced, but _are_ updated, possibly to NIL, by the
garbage collector.

A non-increment/decrement pointer in a reference counted system I
have called a 'deferred increment' pointers.  I have a recent paper
in Sigplan Notices (and my ftp/www archive) which investigates
this issue more thoroughly.
