If you use %pipe% with a program that writes only a few bytes of output and
then is not finished yet, then the PostScript code will not be able to read
it immediately. The %stdin device does not do that; it will read it
immediately. How to fix so that it can be done by a pipe called by the
PostScript program, also, instead of only stdin?
