Comment(by SimonKing):
It turns out that all the patches can still not fix the problem. We also
have to deal with `sage.structure.factory.UniqueFactory`.
I suggest to add an option to `UniqueFactory`, that decides whether a
strong or a weak cache is used. And I suggest to do this ''here'', because
I don't want to create yet another ticket.
The applications of `UniqueFactory` should mainly be in cases where weak
references work. Therefore I suggest to use the weak cache by default - I
am curious how many doc tests will fail...
Coercion sucks.
