Description

See also #6376 #6380. I have some changes that turn the paragraph in [atomics.order] into recommended practice.

An implementation should ensure that the last value (in modification order) assigned by an atomic or synchronization operation will become visible to all other threads in a finite period of time.

- [intro.progress] p18

Implementations should make atomic stores visible to atomic loads within a reasonable amount of time.

- [atomics.order] p10

Firstly, both of these paragraphs should be formatted as recommended practice. Secondly, there is such significant overlap that it may be worth coalescing them into one.

Research direction

Start with [intro.progress] p18 and [atomics.order] p10, then review related issues #6376 and #6380. Compare the overlapping guidance and determine whether it should be coalesced; done means both paragraphs are formatted as recommended practice and the final organization is consistent.
