// When we cancel a write/truncate, we always get back the result of the write

// So we'll get back either
//   success [of the write/truncate, in a DidWrite(XXX, true)/DidSucceed() call]
//     followed by failure [of the cancel]; or
//   failure [of the write, either from cancel or other reasons] followed by
//     the result of the cancel.
// In the write case, there could also be queued up non-terminal DidWrite calls
// before any of that comes back, but there will always be a terminal write
// response [success or failure] after them, followed by the cancel result, so
// we can ignore non-terminal write responses, take the terminal write success
// or the first failure as the last write response, then know that the next
// thing to come back is the cancel response.  We only notify the
// AsyncFileWriterClient when it's all over.
