I apologize. Four messages ago you mentioned "some other shell window", and I somehow misread this to mean that the terminal running dd is not important. So I now retried the whole thing with two xterms, one running the dd, and another running the infloop. I also had a third window running, a Konsole with a blinking cursor. I see the same behavior as previously, when I was using two Konsole windows and Emacs with a blinking cursor. Hm. -- This line is not blank.
