It's not clear that the problem _can_ be solved in user space. It's easy enough to say "never allocate more than a page". But it's often not REALISTIC. Very basic issue: the perfect is the enemy of the good. Claiming that there is a "proper solution" is usually a total red herring. Quite often there isn't, and the "paper over" is actually not papering over, it's quite possibly the best solution there is.
