wait()/wait_for() losing items on Queue.get()

[GoogleCodeExporter]

Re: https://groups.google.com/forum/#!topic/python-tulip/31FktH8h-jk
(TL;DR: How do I use timeouts with "Queue.get()"?)

What steps will reproduce the problem?

The attached script demonstrates that loss of items in producer-consumer 
situation where there are timeouts with ".wait()".

The script will start a producer and a consumer. It will process 100 items.

What is the expected output? What do you see instead?

It is expected that the producer will put 100 items and the consumer will get 
100 items. Instead, the producer will put 100 items, but the consumer will only 
see a fraction of the items.

On my computer, the script will hang with 31 items outstanding. It is expected 
that the script should finish. If you remove line 40 where the producer is 
blocked (causing a timeout on the consumer), the script should complete.

What version of the product are you using? On what operating system?

Python 3.4.0 Ubuntu 14.04

Please provide any additional information below.

This also occurs with Trollius 1.0.
