OK. Thanks for the hint. However BufferedReader.readline() does
not block in Java, so it is still difficult to transpose.

How do people handle this, then? Reading from a process that will
block if you ask too much yet won't let you know how much there is
to read right now has to be some kind of FAQ.

I think it must otherwise you might get incomplete answers or no
answers at the interactive prompt and that never happens. It may
not flush its buffer after every line but it must flush them at
the end of an answer.
