Comment (by Varun Kasyap Pentamaraju):
Hi,
I tried adding the `__del__` method to `ModelState` as suggested.
I also wrote a `gc` test to check for the `OneToOneField` reference cycle.
The test is still **failing**, and the objects are not being collected.
I am worried that adding `__del__` to an object inside a reference cycle
might be preventing the garbage collector from cleaning it up. This
`__del__` approach might not be the right fix here.
