private static void doWork(long tid) throws InterruptedException
{       
                if (!sortedTid.contains(tid)) {
                        sortedTid.add(tid);
                }

               // simulate a straggler, make the thread with the lowest tid a 
slow
processor
                if (sortedTid.first() == tid) {
                        if (counter++ == 1000){
                                Thread.sleep(60,000);
                        }

                        Thread.sleep(20);
                } else {
                        Thread.sleep(20);
                }
}

Just for testing purpose, the thread with the lowest tid sleeps 60s when the
counter reaches 1000. Will 'sleep' causes any issues?
