Bug in kazoo 2.0 library

Question

I am using kazoo in project I am working on. But after some time I get an error message that new connection to zookeper cannot be opened.

So I wrote a little test program:

for i in range(0, 1000):
    print i

    zk = kazoo.client.KazooClient()
    zk.start()
    zk.stop()

And after around 500 iteration I've got an error: "Too many open files".

Am I using kazoo somehow wrong?

Call the close() method. From the documentation:

close()

Free any resources held by the client.

This method should be called on a stopped client before it is discarded. Not doing so may result in filehandles being leaked.

New in version 1.0.

However the example code within the same documentation doesn't call close(), so it's confusing.
