I got this email today off-list. As suggested, killing the program
that's running inside screen does make it reattachable, but this
doesn't really seem like a real solution to me, since usually I want
to see some state that was in screen.

Also, I do use Linux sometimes, and the steps I ran doesn't cause
screen to freeze there.

Thanks,
Karim
