Guido, it's best if Antoine reviewed it - he wrote the relevant PEP, and the code I'm changing.  I'm sure he'll agree it's a necessary change.

About the rarity of the bug, not only do the refcounts and cyclic structure have to be just right, we also need exactly the right parts of the cyclic trash to appear in exactly the right order in gc's generation list.  It really has nothing to do with asyncio.  But it's hard to provoke!  Even knowing the cause, I have yet to create a simple failing test case.
