I'm agree with @Ben James.Try to use both deque and set.

here are code:

class SetUniqueQueue(Queue):

    def _init(self, maxsize):
        self.queue = deque()
        self.setqueue = set()

    def _put(self, item):
        if item not in self.setqueue:
            self.setqueue.add(item)
            self.queue.append(item)

    def _get(self):
        return self.queue.popleft()
