Is three any wrong with the example code of PriorityQueue?

[hiczlf]

from queuelib import FifoDiskQueue
q = FifoDiskQueue("/home/lf")
from queuelib import PriorityQueue
pq = PriorityQueue(q)
pq.push(b'a', 3)
Traceback (most recent call last):
File "", line 1, in
File "/usr/lib/python2.7/dist-packages/queuelib/pqueue.py", line 33, in push
self.queues[priority] = self.qfactory(priority)
TypeError: 'FifoDiskQueue' object is not callable

Should q be a factory generate FifoDiskQueue object?
