[issue22003] BytesIO copy-on-write

[David Wilson]

David Wilson added the comment:

I'm not sure how much work it would be, or even if it could be made sufficient to solve our problem, but what about extending the buffers interface to include a "int stable" flag, defaulting to 0?

It seems though, that it would just be making the already arcane buffers interface even more arcane simply for the benefit of our specific use case
