The consensus was that if you want SeqCst semantics then you should just wrap a pair of SeqCst fences around every queue operation.

applications may need stronger guarantees for e.g. relating multiple queues.
I've chatted with @Amanieu about this. It turns out that:
- Even mutexes can't relate multiple queues (locking is not
SeqCst). - Read operations in reader-writer locks are possibly not
SeqCstdue to lock elision.
Given that, should we strive to provide SeqCst semantics in our data structures at all?

I wonder whether @jeehoonkang agrees. If so, we can close the issue.

I generally don't believe "sequential consistency" can give you much benefit: after all, its meaning is very vague. In this spirit, I'm in favor of closing this issue.
