Sorry, this was nonsense - I hadn't noticed that is was a single
ForeignPtr (in Haskell land) as well as being a single object (in C
Seems like it'd be reasonable to specify an order for these.
An alternative would be to drop addForeignPtrFinalizer. I have no
idea what the motivation for this function is since I can't think when
you'd need/want/prefer to add finalization actions incrementally
instead of doing it in one step. Can someone give a motivating
example where there is some advantage in adding finalization actions
