I hope it is OK that I modified one test in sage.rings.polynomial.polynomial_ring, by the new patch trac9944_addendum.patch​.

That test used to be 

sage: QQ['y'] < QQ['x']
False
sage: QQ['y'] < QQ['z']
True

But that is unsafe, because this ticket removes the custom __cmp__ method of polynomial rings. So, the comparison relies on virtually random data such as id(QQ['x']), if I am not mistaken.

Therefore, it seems safer to me to replace it by 

sage: QQ['y'] != QQ['x']
True
sage: QQ['y'] != QQ['z']
True
