Reference Counting Cannot Break Cycles

import gc

class Node:
    def __init__(self, label):
        self.label = label
        self.other = None
    def __del__(self):
        print(f"{self.label} freed")

gc.disable()

a = Node("A")
b = Node("B")
a.other = b
b.other = a

del a
del b
print("after del")

gc.collect()
print("after collect")

gc.disable() turns off CPython's cyclic garbage collector, so only reference counting is running until gc.collect() is called explicitly. What does this print, in order?
