One of the simplest ways to terminate a thread from another thread is to
interrupt that thread. You can detect the interrupt by catching an
InterruptedException and checking the status of the thread with
Thread.interrupted() or Thread.isInterrupted(). If the thread is
blocked on I/O you can usually close the stream and force a IOException.
