Just a quick look, but I betcha it has to do with buffering.
After writing the line to the pipe, call the flush() method on
the output pipe and see what happens there.
(Pipes buffer differently than regular output so this is a
common mixup, especially with IDEs which communicate with
stdout via pipes normally!)
let me know if it works
Impressive reply speed! :)
However calling pipes.stdin.flush() immediately after writeln did
not seem to work.
