Could it be this: Initially wait == notify == 0
Waiter Signaler 479 atomic.Xadd(&l.wait, 1) = 1 522 atomic.Load(&l.wait) = 0 atomic.Load(&l.notify) = 0 523 return (because those above are equal) 485 notifyListWait(l, t) (blocked forever) But looking at your answer, I see that you may imply certain race conditions are allowed. Could you explain a bit more on that? Aren't race conditions supposedly bad? If atomic load should always returns the last atomic write to a memory location and if I make absolutely sure that the last atomic write finish at a specific time instant earlier than the atomic load, I can never get data written before that last atomic write, is that what you meant? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
