Hi Jérôme,

very ugly. Ideas welcome.
Something else that may need to be considered here: for a 32-bit process,
any memory mapping-related operations (mmap, loading executable images into
the team's address space, etc.) need to take into account that the area
needs to fit within the bounds of a 32-bit virtual address space. Not sure
what changes that would entail on the kernel/VM side for that right now.

Rene
