PyCell_GET/SET are not thread-safe in free-threaded builds #127271
Description
Bug report
Bug description:
The PyCell_GET and PyCell_SET macros are not safe for free-threading builds. First, they don't the correct locking. Second, PyCell_GET returns a borrowed reference.
For CPython internals, the usages of these macros can be replaced (either with PyCell_GetRef(), PyCell_SetTakeRef(), or similar). For external API users, these macros will need to be marked as deprecated, at least for free-threaded builds.
