I suppose that I could add a C object as an attribute that points to a block of memory that contains copies of all my workspace pointers, and use the object deallocator to clean up. If all else fails, I will try that, but it seems a hell of a long way round for what I would have thought was a basic requirement.

Well, you could use a custom metaclass with a tp_dealloc or whatever. But I just mainly meant that a PyCObject is almost as good as a weakref for certain purposes -- i.e. it's got a pointer and a callback.

You could of course also use weak references, but that's a bit more awkward as well.
