Message 402850 - Python tracker

Assuming that issue 45256 is implemented, we will need to document it.

I'm opening a separate issue, so this doesn't get lost in the midst of 45256.


We need to:

Document the changes to gdb. Possibly at https://wiki.python.org/moin/DebuggingWithGdb, or in the main docs.

Add a "what's new" entry explaining what the impact of this change is.
