The writing process is not a PostScript program, but a C program; the
PostScript program is reading the output from it. (Note that it does
not do this with standard input (even if it is connected to the same
C program); it only does this with a pipe. (The C program does flush
the output. The PostScript program is doing input; it does flush stdout
but that doesn't affect the %pipe% at all.)
