The idea is to call all del's before any object in the cycle is deallocated (that is, call them manually rather than as part of deallocating them). That way you shouldn't have the issues mentioned above.

Firstly, as I said above: you will still have del ordering issues. Secondly, the destructor itself currently calls del, so if you call del before any deallocation, it will get called again as part of the deallocation. Might be a technicality but it will still probably require some code restructuring to work around (or making that code even more hairy).
