Shared structures are:
At the process level:
        -> File system (only matadata and data caches)
        -> Task manager table
        -> Task vm_region if we support inter process com (not the case in almos)

        specific to ALMOS:
        -> DQDT to allocate the approprite proc/mem ( can be avoided for now by directly using the
        the task next_cluster field, and always redirecting the allocations to the local cluster)
        -> 


Efficient com with other proc:
        - devellope physical access techniques at the software level
                - fine grained at the C language level
                - at the assemebler level, by inserting macro to switch space
        - get some help from the hardware (put an paddr_extension for the stack (most important) and
          one for the instructions (secondary) )
