	Subject: [PATCH] login: use TCSANOW to remove HUPCL

	login(1) code:

		ttt.c_cflag &= ~HUPCL;
		tcsetattr(0, TCSAFLUSH, &ttt);

		close(STDIN_FILENO);
		close(STDOUT_FILENO);
		close(STDERR_FILENO);

		signal(SIGHUP, SIG_IGN);        /* so vhangup() wont kill us */
		vhangup();
		signal(SIGHUP, SIG_DFL);

	strace :

		ioctl(0, SNDCTL_TMR_CONTINUE or SNDRV_TIMER_IOCTL_GPARAMS or TCSETSF, {B9600 opost isig icanon echo ...}) = 0
		close(0)                                = 0
		close(1)                                = 0
		close(2)                                = 0
		--- SIGHUP {si_signo=SIGHUP, si_code=SI_KERNEL} ---
		--- SIGTERM {si_signo=SIGTERM, si_code=SI_USER, si_pid=1, si_uid=0} ---
		+++ killed by SIGTERM +++

	It seems we get SIGHUP (and SIGTERM from systemd) before vhangup().
	The problem occur sometimes.

	I guess it's because TCSAFLUSH is not applied immediately, so it would
	be probably better to use TCSANOW to make the code more robust.
