Does this prevent us from using any memory in the user process above 
the 32-bit boundary?  Or can it still be mapped/allocated with the 
stack region just treated as "already allocated"?

Some of the indications from the Linux camp suggest that if you give 
people access to more than 4G of process address space, they're going 
to use it.  Precluding this would be somewhat of a lose.
