* Forker will fork ncopies-1 copies of self.
* arg 1: Number of copies of the process to be running after return.
* This value minus one is the number of forks performed.
* arg 2: mode: 0 - all children are first generation descendents.
* 1 - each subsequent child is a descendent of another
* descendent, resulting in only one direct descendent of the
* parent and each other child is a child of another child in
* relation to the parent.
* arg 3: prefix: string to preceed any error messages. A value of NULL
* results in no error messages on failure.
* returns: returns to parent the number of children forked.
