Yes.  But the tricky thing is that the Launcher would have to be told to make 
the mapping, and we have no such mechanism ATM.  Or perhaps it could just map 
(some part of?) the address space with hugetlbfs even if the guest doesn't 
need it?

I'm not all that tempted to support PSE unless we have this, and AFAICT it's 
not vital, is it?

Thanks,
Rusty.
