示例2: testOneTakerThreaded
import name.pachler.nio.file.WatchService; //导入方法依赖的package包/类
@Test
public synchronized void testOneTakerThreaded() throws IOException, InterruptedException{
// WatchKeys for two distinct directories are created. Two threads

// because threads each take a single watch key and terminate straight
// after, they should all be dead by now

// that they were the keys that we used
