SOLVED:  I have 'ARGV.concat [ "--readline" ]' in my .irbrc file, and I'm guessing that you don't 
because if I comment out that line and run the tests, it works swimmingly.

However, changing it to use STDIN gives no errors, and your right it does seem to be whats causing
the hang to infinity as it waits for the user to hit enter.

What color are the boots of christ? (Yes/No/Quit):

I have `ruby -v`

        Hmm.  For me in my environment, if I don't use STDIN I get these errors: 
        http://gist.github.com/201570 .  If I change it to use STDIN, the errors go away
        but it seems to cause that hanging forever problem.  Whats different between our
        two systems?  I do my tests on Shmee which runs Debian, you run Debian.  I have
        no packages available for upgrade (or dist-upgrade).

        I think the problem is that it was using STDIN.gets, instead of just gets, so
        overriding $stdin made no difference. It was probably hanging waiting for enter.

        I've removed the STDIN and it should just work...

        The test code is now hanging for me, so I left it commented out. It's a problem
        with wrap_io... I'll look into it.

        That part of the code has been commented out in commit
        c6fd71bf05fd8fb0a78928dc9986ffe61f4ce453.  wnight reports it does not hang for
        him...?
