- secondcoming 6y ago"Where is the bug? Worker 2 wasn’t supposed to go to sleep, because g_signals[0] was supposed to be 2. So the “compare” part of the “compare and wait” of the futex should have returned false. But Worker 1 came back from the past and did a decrement of g_signals that should have belonged to a previous generation"
