Review comment:
Instead of doing .run() we can define pauseTask as
```
private volatile Future<?> pauseTask =
CompletableFuture.completedFuture(AWAIT);
```
and cast it in ``pause`` method to ``RunnableFuture`` like this
```
updateQueue.offer((RunnableFuture<?>)(pauseTask = new FutureTask<>(() ->
AWAIT)));
```
