Comment (by SimonKing):
Trying an explanation:
#715 plus #11521 in their original versions resulted in trouble. A
solution (that is not acceptable for my own work, but might be OK for
"usual" applications of Sage) is to re-instate the strong cache of
polynomial rings - see the last patch on #715.
If I am not mistaken, #715 plus #11521 in these versions have a positive
review, without #13447.
Now, why did I put #13447 as an explicit reference at #12313? I guess that
is because (1) I thought that #13447 is close to being fixed (I was
mistaken...) and (2) the patchbot got confused by the circular dependency
#715 <-> #11521.
But who knows. I am currently not really in the condition to do coding.
