If this is be thread1, then as a consequence, thread2 cannot succeed at m.lock() before thread1 has executed m.unlock(), consequently A happens-before B in this case. By symmetry, if thread2 succeeds at m.unlock() first, we can conclude B happens-before A."" In the last sentence, that should probably be ""... if thread2 succeeds at m.lock() first, ..."". That is, change ""unlock"" to ""lock""." Bugs closed To Be Determined atomic Boost 1.54.0 Cosmetic fixed
