Fabric displays Disconnecting from username@server... done. for almost 2 minutes prior to showing a new command prompt whenever I issue a fab command.

This problem exists when using Fabric commands issued to both an internal server and a Rackspace cloud server. Below I've included the auth.log from the server, and I didn't see anything in the logs on my MacBook.

Any thoughts as to what the problem is?

Thoughts on Cause of the Issue

1. I don't know how long the problem has existed. However, I know that at one point I didn't have this problem. Things that have changed since then are that I have recreated my virtualenv's using virtualenv 1.4.7, virtualenvwrapper 2.1, and pip 0.7. Not sure if this is related, but it is a thought since I run my fabfiles from within a virtualenv.
