Thinking it over and going back over some references

threads here (e.g. much earlier ones from Olivier et al) it does seem
that this should be enough. This particular situation isn't so
complicated after all. I think the more I read earlier during this
thread (and reading around) generally about memory ordering, the more
I was beginning to feel as if the entire subject was a source of only
trouble.
Quite interestingly, I have noticed that discussions about memory barriers are
often somehow endless. What happened in the past is that I saw countless
discussions about whether they are needed, whether they are not, and people
would argue a lot and passionately. So I thought, maybe there's a hidden topic
behind that. A "memory barrier"... Well, that very much reminds me of this
memory loss which happens to all of us in the childhood. It turns early years
into fuzzy memories. That is a barrier, too.
Whether such psychological barriers are needed or not, that's an interesting
question :)
