Another point (besides the inherent limitation on the amount of data passed
over the pipe) that no one has mentioned:

   *  If the program exits abnormally FOR ANY REASON the temporary file(s)
      will not be erased.

Everyone is willing to offer their own kludgy implementation, to try to show
off, rather than admitting that DOS just doesn't fit pipes.  [B-)]
