[issue35502] Memory leak in xml.etree.ElementTree.iterparse

[Serhiy Storchaka]

It is not easy to avoid reference cycles if use a generator function. And generator function is much faster than an implementation as a class with the __next__ method. We need to access the iterator object from the code of the generator function, and this creates a cycle.
