…racebacks.
This is part 1 of issue
python#107. If you unpickle a traceback object, Stackless now reconstructs the f_back links of the assorted frame objects.
There is also a new test case in test_pickle.py.
Manually grafted from pull request
python#22.

There were some grammatical errors in weakref.WeakValueDictionary

Same as #10, backported to 3.6 branch
