    // To ensure that every task agrees on which tasks are alive, the

    // GetAliveTasks(T) for a set of tasks T. The invocation acts as a barrier,

    // One small correction. GetAliveTasks doesn't act as a barrier for *every*
    // task in T. Some tasks in T might have failed, so we should not wait for
    // them. Instead, the GetAliveTasks RPC waits only for the returned tasks A.

      // To ensure that every task agrees on which tasks are alive, the

    // # Barrier Semantics
    //
    // If multiple tasks call GetAliveTasks concurrently, it's important that they
    // all agree on which tasks are alive. Otherwise, the tasks' behavior might
    // diverge. For example, imagine a set of tasks trying to run an AllGather,
    // but they all disagree on which tasks should be participating in the
    // AllGather. This is buggy.
    //
    // To ensure that every task agrees on which tasks are alive, the
    // GetAliveTasks RPC has barrier-like semantics. Consider an invocation
    // GetAliveTasks(T) for a set of tasks T. The invocation acts as a barrier,
    // waiting for every task in T to call GetAliveTasks(T). Afterwards,
    // GetAliveTasks returns the same set of alive tasks A to all the tasks in T.
    // This ensures that every task agrees which tasks are alive.
    //
    // One small correction. GetAliveTasks doesn't act as a barrier for *every*
    // task in T. Some tasks in T might have failed, so we should not wait for
    // them. Instead, the GetAliveTasks RPC waits only for the returned tasks A.
    //
    // # An Example
    //
    // Imagine we have four tasks: A, B, C, and D. Further imagine that task D
    // has failed and that every task calls GetAliveTasks([A, B, C, D]). The
    // invocation will return tasks [A, B, C]. The GetAliveTasks call acts as a
    // barrier across tasks A, B, and C. Task D, which failed, is ignored.
