If it ever worked, it has to be a Qt4.x->Qt4.y thing.

We probably want an 'allowSleep()' in systemwatch which does the right
thing for every platform. On OS X, you prevent sleeping by reacting on
the 'sleep' request. On windows, it would trigger a periodical call of
this api.

As for the UI thing, we indeed want something like that in the future.
