        That was one of the problems I was having: overwriting the memory
    you already have is easy, but moving... I mean, you realloc and move
    the memory but the kernel doesn't notice it, am I wrong?

        Exactly ;)

        I'm VERY interested, but the problem is that in any case I won't
    be able to use that in my programs since portability is sometimes an
    issue :( Not all OS are able of such things. The problem, in the end,
    is that changing the name of the process is not a standard thing...

        Thanks for your help :)
