Surly not, I just thought, there might be an easy way to make this

Ok, I see - I already thought about this. It just didn't felt right,
because I see ProcessKey() as some kind of message loop, which I don't
want to give too much responsibilities. In my current design, the menu
has a presenter (MVP), which is an observer that get's notified by the
thread. I will probably let the presenter collect the items to be
updated and when the menu comes across a kNone in ProcessKey, it lets
the presenter update any items it may have in it's "update queue".
Surely not the best solution, but maybe I will find a better one later on.
