An alternative would be something like the following. It is definitely
less hackish but it steals one bit in mm->flags. We do not seem to be
in shortage there now but who knows. Does this sound better? Later
changes might even consider the flag for the victim selection and ignore
those which already have the flag set. But I didn't think about it more
to form a patch yet.
