    avoid allocating finalizer data for symbols in weak sets
    
    * libguile/weak-set.c (symbol_finalizer, register_finalizer): Add a fast
      path for symbols, to avoid allocating the finalizer data.

    reimplement guardians in terms of chained finalizers and weak tables
    
    * libguile/guardians.c: Reimplement in terms of chained finalizers and
      weak tables.
    
    * test-suite/tests/guardians.test: Add test for weak mappings added
      after registering an object with a guardian.

    reimplement weak sets using finalizers instead of disappearing links
    
    * libguile/weak-set.c: Reimplement using finalizers.  Removes the need
      for the periodic vacuum_table calls.

commit 543328b5aed9b4898e2943b3ae3718f5c786491f
Author: Andy Wingo <address@hidden>
Date:   Sun Feb 19 12:51:53 2012 +0100

    reimplement weak tables using finalizers instead of disappearing links
    
    * libguile/weak-table.c: Rewrite to use finalizers instead of
      disappearing links.  This will allow weak table associations to
      persist beyond resuscitation of an object by a guardian.  It also
      removes the need to periodically vacuum the table.
    
    * test-suite/tests/guardians.test: Add test for weak maps persisting
      across guardian resuscitations.
