With your patch I don't see a leak for refleak.py, but I still see one for 

./python.exe -m test -R 3:3 test_exceptions -m test_no_hang_on_context_chain_cycle2 -m test_recursion_normalizing_infinite_exception -m test_recursion_in_except_handler -m test_recursion_normalizing_with_no_memory -F -j1

(once I remove the @skip on test_no_hang_on_context_chain_cycle2). 


However, if I make this change it looks better:
