07:41 PM Ruby Feature #9145: Queue#pop(true) return nil if empty instead of raising ThreadError

How about a block form where the block is called with the popped element? The method would return false if called with non_block set to true if the queue is empty.
q = Queue.new
q << 1
q << 2
q << 3
while q.pop(true){|x| p x}
