CVS via SSH issues

Okay, maybe I'm doing something _completely_ wrong in here somewhere, but
I'm experiencing problems doing a CVS checkout operation via SSH. Either CVS
or SSH is hanging after checking out the last file in a module. Here's the
scenario:

     [mondoshawan@nadesico:~]$ echo $CVSROOT
     :ext:mondoshawan@thing:/var/cvs
     [mondoshawan@nadesico:~]$ echo $CVS_RSH
     ssh
     [mondoshawan@nadesico:~]$ cvs co common
     mondoshawan@thing's password: 
     U common/classes/srep/live/MsgTopicPostable.php
     U common/classes/srep/live/Nav.php
              (...ad infinitum...)
     U common/functions/session.php

Just after dealing with that last file, it hangs. It just so happens that
common/functions/session.php is the last file it needs to checkout. When I
do the checkout locally on Thing, I don't have any problems. Additionally,
other coworkers don't have this issue (both Mac OS X and Debian Linux), so
I'm guessing it's an issue on my local machine. Any ideas?
