Possibly crazy idea to deal with memory layout problems once and for all

Without the hack, Age of Mythology gets an out of memory error in the current 
git code even before it gets to the main menu. There is sufficient memory, 
it's just that everything above TASK_UNMAPPED_BASE is badly fragmented  so 
that there is no unmapped virtual address space of sufficient size in the 
available range.

I would be surprised to see an app care about what is in bit 30 of an address 
- bit 31 perhaps, but bit 30 should not make a difference except perhaps in 
the case of comparing unassociated pointers. Is this infererence about WoW 
based on discovering code that has such a sensitivity?
