Yeah yeah I know, indeed I think I pointed it out in the message which
started this whole discussion. In the example application I am thinking of,
I think cycles can be excluded in the first instance. In general I think
there are various rather complicated things one might do in the finalizers
to deal with cycles, and frankly I'd rather be able to write the code for
this in Haskell rather than in C.
