两种方法有什么区别？在哪种情况下，应该使用另一个？
/**
* Wait for the asynchronous operation to complete with the specified timeout.
*
* @return <tt>true</tt> if the operation is completed.
*/
boolean await(long timeoutMillis) throws InterruptedException;
对战
/**
* Wait for the asynchronous operation to complete with the specified timeout
* uninterruptibly.
*
* @return <tt>true</tt> if the operation is finished.
*/
boolean awaitUninterruptibly(long timeoutMillis);
