Another spin of this patch, now in multiple pieces.
There was no performance hit for forking the hugetlbfs mapping creation
on x86_64 or x86, as can be seen below (averages of 5 runs), nor for
64-bit binaries.
Many thanks for Adam, Nish and David for the education while working
through this problem.
