    Speaking about messing up; also writing to 2 bytes located after each
    other by 2 processors can mess up things. On a Sparc processor for
    example.
    e.g.:

    char dummy[2];

    when processor 1 writes to dummy[0] at the same time as processor 2
    writes to
    dummy[1], you'll get into trouble.

    ...

    Ehrm, I'm not sure why I wrote it down here since it has nothing to do
    with the
    thread. Sorry for that, probably my ego needing some boost.
