Hello python-dev.
I'm working on a patch to remove reference cycles from heap-allocated classes:  http://bugs.python.org/issue17950
Part of the patch involves making sure that descriptors in the class dictionary don't contain strong references to the class itself.
This is item 2) in the defect description.
I have implemented this via weak references and hit no issues at all when running the test suite.
But I'd like to ask the oracle if there is anything I may be overlooking with this approach?  Any hidden problems we might encounter?
