--- Comment #2 from Jacob Lifshay <programmerjake at gmail.com> ---
I added a new MemMMap class.

I also added a method that the syscalls should use when they need direct access
to the memory (method not yet tested, I'll add that next):
class MemMMap:
    def get_ctypes(self, start_addr, size, is_write):
        """ returns a ctypes ubyte array referring to the memory at
        `start_addr` with size `size`
        """
