Quite intersting. Appears that the CPU usage problem only appears after you've tweeted with the widget. If I just add the widget (after killing it from x-term) and leave it, it uses no cpu. If I then tweet something from the widget, it will get stuck and use as much cpu it can get it's hands on.

I guess this goes under Maemo Official Applications, so I'm posting a bug. link soon.

EDIT It's not..
