#447: Inconsistency when calling set-finalizer! multiple times on the same 
object

 The following program prints "b" when interpreted and "ba" when compiled:

 {{{
 (define x (list 1))
 (set-finalizer! x (lambda (x) (display 'a)))
 (set-finalizer! x (lambda (x) (display 'b)))
 (set! x #f)
 }}}

 I am not sure whether replacing the existing finalizer or appending
 another finalizer makes more sense. However, it would probably be better
 if both cases behaved the same.
