tty.getWindowSize() always returning 80 - not [width, height]

[dylang]

Issue
tty.getWindowSize() is always returning 80.

Expected
tty.getWindowSize() returns array [width, height].

Seen in Node 0.6.2 on Mac/OSX using iTerm 2. This function works as expected in Node 0.4.12.

use process.stdout.getWindowSize() now

Should we update the docs? I can create a pull request.
