public final class RunnableErrorForwarder extends Object
Error or RuntimeException from a Runnable executed in
 a worker thread back to the parent thread. The simplified usage pattern looks like this:

 for ( Runnable task : tasks )
 {
     executor.execute( errorForwarder.wrap( task ) );
 }
 errorForwarder.await();
