Recycles or deletes an object that is no longer used.
Note: Strictly specking old should be a ref to satisfy D's delete
expression which wants the pointer as an lvalue in order to set it to
null after deletion. However, would make code more complex and isn't
actually necessary in the particular use case of this interface (see
BucketSet.remove()/clear()).
