IO buffering won't work the way they expect when they don't have a
real console.  So, you wind up with weird conditions like the program
waiting for input after printing out a prompt - but the app didn't
call fflush(), so the prompt hasn't actually been displayed, but it's
still waiting for you to answer the question.  Using them in a
scripted way should work fine, it's just interactive usage that you
would expect to be broken.
