OK. I see no point to this kind of virtualization that has been designed 
to make several OS coexist on the same hardware (e.g ADEOS, RTLinux, 
...) without really modifying the OS originnal code. It hads overhead 
and slowdown without actually solving our initial problem that is 
defining an API is a kind of virtualization by its own.
