Piping on Windows is not much different than on Unix. You should only have *one* open file descriptor. If the subprocess needs to read from stdin, then stdout and stderr should be redirected to a file. Otherwise you can get deadlocks, because the buffers have a finit size. AFAIK ">file" and "2>file" does work on windows. On Unix you can the module "select".
