To answer at least the question WRT TIOCGETA. To determine whether
a file descriptor is a tty you can use the function isatty() which
doesn't do anything but "tcgetattr(fd, &term_struct)" and if that
fails, it returns false. As you've already guessed the latter
function isn't nothing else but a ioctl() with TIOCGETA. So, isatty()
is used by stdio functions and that explains the noise in trace logs.
