We have several tests where we check refcounts that are failing in Python 3.14 beta 4.

Apparently this is expected, see
https://docs.python.org/3.14/whatsnew/3.14.html#incompatible-changes
https://docs.python.org/3.14/whatsnew/3.14.html#whatsnew314-refcount

We'll need to fix the tests to release on 3.14.
