Assuming the weak pointers solution is the way to go, I've been re-aquainting myself with System.Mem.Weak and now I'm now wondering what is an appropriate key for each ForeignPtr.

Would it be OK to use the ForeignPtr itself as it's own key? (Seems OK to me, but this is a bit different from the memoisation example so I thought I'd check.)

I guess I should've taken a look at mkWeakPtr :: k -> Maybe (IO ()) -> IO (Weak k) before asking this :-) Regards -- Adrian Hey
