Could we change this method to smth like StartThrobber(ThrobberManager*)? Thus
each UserInput would choose where to put the throbber without exposing bounds to
the caller. Caller won't have to treat the return code of this method
differently then.

I went further and implemented class that exposes start/stop interface.
