In most Unixes you'd be better off using the ioctl() call (the
details of which I can't remember at the moment -- I thought it
was in the termios struct, but I can't find it).  The
environment variables are frozen at the time your program is
invoked and won't reflect any window resizing done since then.
If you start with the os.environ values you should then catch
SIGWINCH signals that are sent when the window is resized.
