Why isn't SO_REUSEADDR working for multiprocessing.Listener?

I'm building an application that communicates with another script using the Listener/Client classes of the multiprocessing package.

I can successfully create both the listener and client, and communicate, however I am still receiving the lasting effects of the TCP TIME-WAIT - after I rerun the script I get the exception when instantiating the listener:

[Errno 98] Address already in use

I have no idea why this is happening, because as far as I know, by default SO_REUSEADDR is set in the constructor for Listener (see Lib/multiprocessing/connection.py).

I'm running Ubuntu 12.10 and using Python 2.7.

This normally happens when you don't close the socket cleanly. Can you post some code showing that you're closing the socket cleanly, even if you force-close your application?
