rl.pause()
rl.pause() 方法会暂停 input 流,以便在必要时可以稍后恢复。
【The rl.pause() method pauses the input stream, allowing it to be resumed
later if necessary.】
调用 rl.pause() 并不会立即阻止 InterfaceConstructor 实例发出其他事件(包括 'line')。
【Calling rl.pause() does not immediately pause other events (including
'line') from being emitted by the InterfaceConstructor instance.】
