Unfortunately you can't really do the same thing on an MPE/iX machine
because physical memory is allocated in 4Kb "pages".  If you have a
1Mb stack in memory, it may be stored in a totally random set of 256
pages.  It makes no difference to the hardware whether those pages are
contiguous or randomly distributed throughout physical memory.

To complicate things further, not all of the pages have to be in memory
at once, whereas MPE/V moved entire segments in and out of memory and
had to find a contiguous chunk of memory to load each segment into.
