Following long discussion in SG1 about P3255R1
https://lists.isocpp.org/parallel/2025/09/4624.php

We agreed that the notes about "shared memory" is vague and cannot be relied on. The standard does not mention anywhere about two processes with shared memory. This note will have conflicts with the meaning of lock free that is proposed in P3255R1. Since this note is not useful, let's remove it editorially.

Can Olivier Giroux verify the change?

Since many of SG1's load-bearing specifications seems to come in the form of notes, I think it might be prudent to ask SG1 to file a core issue for this to record this justification.
