- Fix problems with ASs and INTs (see kl/cxsw-1.s and xlib/exc.s)
        Done! At least it doesn't crash :)
        Must check in some way if the stack is correct or not...

- verify that only the needed .o files are linked (see -DPROFILE); provide
        a lightweight implementation of ``message'' (currently remapped on
        cprintf) that does not require linking libm

- profile and optimize the event management code

- rewrite cons.c isolating the parts making assumptions on memory spaces and
        improving efficency (window-based functions can be implemented
        separately)

- pentium timestamp conter code... Integrate it in timer code and event
        management
                                        Assigned to Gerardo

- provide some macro for int-based and call gate-based system calls

- begin to implement some serious code using OSLib:
        1) some simple multithreading executive based on cooperative and
                preemptive scheduling, message-based or based on shared
                memory and semaphores...
        2) some real small kernel, separating it from application code
        3) as 2), but with different address spaces for kernel and
                application
        ...

- fix the eXtender in order to be fully multiboot compliant (no extension to
        the standard multiboot structure: we can use memory maps). Upgrade it
        to the latest version of the standard. Implement modules loading
  == Some work has been done... Now the eXtender can load MB compiant images
     and manages modules.
     o Still to do: the memory map stuff & module parameters
