// I probably should have this code in its own method, to explain the intent with a proper method name... 
while (true) {
  try {
    Thread.currentThread().join();
  } catch (InterruptedException f) {
    //ignore                        
  }
}

// I also first thought I was on crack when I wrote these lines... Yet, as it turns out, this code is correct!
