At some point I thought of replacing get_child_end() and get_parent_end()
with get_read_end() and get_write_end(). While stdin/stdout/stderr could
then pick the right methods for a pipe automatically what would be the
read and write end of the stream behaviors inherit or close? That's why I
left it as it is. Any other ideas?
