While it's true that it doesn't matter if the purpose of the interruption was only to interrupt the `close()` invocation, couldn't this `close()` operation be one of several different "shutdown" actions the thread is taking, some of which do throw `InterruptedException`, in which the purpose of the interruption is to interrupt any or all of them? In that case, you'd want the interrupt to "hang around" so it can happen if/when the next interruptible operation occurs.

In the example below, if the interruption just happens to occur during `Process.close()`, you want an `InterruptedException` to be thrown by `thing3.shutdown()` immediately (or as soon as possible):

try {
    thing1.shutdown();    // throws InterruptedException
    process2.close();     // does not throw InterruptedException
    thing3.shutdown();    // throws InterruptedException
} catch (InterruptedException e) {
   // bail out now
}
