Fork applications with huge pages !

Hey all !
Recently I read a to do related huge pages on linux-mm.org the statement being :
"Fork of an application with huge pages when no huge pages are left - must fail over to small pages."
- Firstly,according to COW whenever the write is occured then the copy of huge pages will start
- Now if no huge page is left we need to go for 4Kb pages....But the application requires the huge page !
- One solution for this might be to use bunch of 4Kb pages to satisfy the requirement....Moreover there is no demand paging or swapping concept for huge pages !
Will this topic be feasible to go forward to....?
