[issue33607] [subinterpreters] Explicitly track object ownership (and allocator).

STINNER Victor added the comment: I see two options: * Add a field to PyObject, but only in a special debug mode. Maybe not even in Py_DEBUG (since I managed to make Py_DEBUG ABI-compatible with the release mode!) * Add an hash table mapping an object to its interpreter. The hash table woul

Antoine Pitrou added the comment: I agree with Victor, we shouldn't add PyObject fields that only have use in certain (minority) situations. The idea of tracking per arena will be non-trivial to implement, as only small objects (smaller than 512 bytes) use our own allocator; larger objects g

Eric Snow added the comment: Note that I wouldn't call this issue absolutely specific to subinterpreters. The "ownership" part is, but tracking the allocator has practical application under a single interpreter. I suppose I could split this issue apart. I lumped the two together because I

Nick Coghlan added the comment: Rather than tracking this per object, you could potentially track it per arena at the memory allocator level instead. Then if you really need the info (e.g. when running the debug allocator), you can check it in a reliable way, but in the normal case, you assum
