Do you mean does *not* happen on darwin12? > Sampling the run after ~40 minutes gives: There's no need to wait 40 mins, the process will be deadlocked after a few milliseconds. I can't look into this for a week, but it looks like notify_all only woke one of the nine threads waiting on the condition variable, which would be a darwin bug. That looks more likely if it doesn't happen on later versions.
