| * This class lets one more easily use |grpc_completion_queue|. To use it, pass the value of the |
| * |unmanagedQueue| property of an instance of this class to |grpc_channel_create_call|. Then for |
| * every |grpc_call_*| method that accepts a tag, you can pass a block of type |
| * |GRPCQueueCompletionHandler| (remembering to cast it using |__bridge_retained|). The block is |
| * guaranteed to eventually be called, by a concurrent queue, and then released. Each such block is |
| * passed a |bool| that tells if the operation was successful. |
| * |
| * Release the GRPCCompletionQueue object only after you are not going to pass any more blocks to |
| * the |grpc_call| that's using it. |
