As I said, it's not a problem of whether read-acquire should be used or not, of
course I thought so, for the first time. But now I see what problems are, as I
already answered to TJ. The work which makes read-acquire work well is
worth itself. But, problems we should focus on now is that manual acquire(work,
wq) should be replaced with others or removed.
