euh: mremap ? Même si ce n'est pas super portable ...

It can fails especially if you disallow adress change ...

I would access all mmapped data through an indirection and let mremap
move the data
... On systems without mremap, I would unmap and mmap ...

By the way, if the file is large, you could mmap it partially only, on
demand ...

Cheers,
Christophe
