New submission from STINNER Victor <vstin...@python.org>:

I recently added PyThreadState_GetFrame() and PyFrame_GetCode() functions to 
the C API of Python 3.9.

Currently, these functions return borrowed references.

I asked on capi-sig and Brett confirms that borrowed refrences should be 
avoided:

Borrowed references should be avoidedd!
https://github.com/vstinner/misc/blob/master/cpython/pep-opaque-c-api.rst#borrowed-references

I will work on a PR to modify these functions to return a strong reference 
instead.
