Thread-safety #913
Description
I saw there was a recent comment on this, so I think the WG would like to push this forward. Summarizing my thoughts ... I think we need a much larger change if we really want to clarify the thread safety guarantees of SYCL. I think John and I agreed in the comments above that we need to go through the APIs one-by-one and decide exactly what thread safety guarantees we expect.
If we are looking to merge this PR quickly as a step in the right direction, I'd be happy with this PR if we delete the non-normative note. I think the note (as written now) makes the wording more confusing, not less.
