@RalfJung I don't think there is a better way to convey the information required for PR #155491, so could you please weaken the wording to make clear that this is only for self-modifying code and would not disrupt the mechanism used for PR #155491?  There's no reason we couldn't strengthen it later if a better mechanism for passing that scheduling information is discovered later.
