Thread fence not only establish synchronizes with relationships, there are semantics of fences that are expressed not in terms of synchronizes with relationships (for example see 32.4 [atomics.order] p.5). These semantics also need to apply to the use of atomic_signal_fence in a restricted way.
[Batavia: Concurrency group discussed issue, and is OK with the proposed resolution.]

Moved to Tentatively Ready after 5 votes.
Change 32.9 [atomics.fences] p. 6 as indicated:
6 Effects: equivalent to atomic_thread_fence(order), except that
synchronizes with relationshipsare established only between a thread and a signal handler executed in the same thread.
