Very useful, posting there was a good idea.

If you send something immediately after an interrupt then it should be
part of the next command, right? I tried to send sync _before_ the ^C
and that simply didn't show up in the output. I guess there are some
strange race conditions in this region.

I pushed a new attempt at this in the expect-fixes branch. It first
matches a random string then the new prompt as distinct stages. This
seems to avoid races. Link to code: http://alturl.com/tf7u

Please test this; it was broken before.
