Never balancing highmem pages will also mean that they never get swapped out. Which makes sense - why should we try to page anything out if we're not interested in having any free pages for that zone? So at some point the VM subsystem will just give up: 90% of the pages it sees are unswappable, and it still cannot make room to free pages..
