demonstrate injection of breaking messages

[2] OTOH a too big body_linecount causes not only messages to be stuck on the
queue but also hanging exim delivery processes. The message content will not
fill the announced chunk size and the remote sits there waiting for exim to
finish the message transmission.

Just inject a message with loads of \r and no \n and watch the delivering exim
process hang when it tries to deliver the message via BDAT. Example script
attached.
