Without the patch we're not sending SIGWINCH at all. ioctl(tty, TIOSWINSZ,
...) supposed to send SIGWINCH if the window size changed. The ioctl() call
should work in the same way for both master and slave ends of pseudo tty,
without the patch the ioctl works for master end only, but many unix
programs (screen for example) change the window size of the slave end.
