Where do you test for the UNDEF that ->dequeue_nb returns when it hits the end of the queue?

To quote Thread::Queue
"dequeue_nb The dequeue_nb method, like the dequeue method, removes a scalar from the head of the queue and returns it. Unlike dequeue, though, dequeue_nb won't block if the queue is empty, instead returning undef. "

    Arg if you read the previous reply ignore it. I need to read more clearly. I am using the Queue's pending function and testing for that in the while loop. Like I said the loop breaks cleanly. it just hangs in the sub though for some reason.
