stack: grow on page fault
...
The steps of the technique to replace stack with hugetlbfs map are as
follows:
(1) Prepare a hugetlbfs map with the size of rlim_cur
(2) Copy the active region of the stack to the hugetlbfs map.
The range to copy is determined by reading /proc/[pid]/maps.
(3) Replace the stack map with the hugetlbfs map
The step (2) tries to copy a huge region if McKernel doesn't grow the
stack at run-time.
