Disabling Gnome Terminal Blinking Cursor

Looking at powertop, an idle Gnome Terminal is waking up around twice a second just to animate the blinking cursor. While this is a minimal amount of wake-ups a second, it still sucks power and also I find a blinky cursor a little annoying. To disable cursor blink for the Default profile run gconf-editor and set /apps/gnome-terminal/profiles/Default/cursor_blink_mode to off.
