    vfork was a good idea when you didn't have a memory management
    unit. Then you had to copy over and possibly re-link the existing
    process to a new place in memory. That was a costly process. Yes Unix
    did run on that kind of hardware in the eighties.

    Nowadays the overhead is almost non-existent, so it is not neccesary
    to make the distinction....
