Because it ought to.  RTFM.  If you're talking about the UNIX fork(2)
system call, it yields one of three results:
    -1 => something went wrong, we've still just one process and this is it
     0 => forking worked, and _this_ process is the child
     N => forking worked, _this_ process is the parent, and the
	  child process has process it N.  If you are going to wait for
	  the child to finish, you _need_ this number.
(Look at the DIAGNOSTICS section of the fork(2) manual page.)

Um, if you're a Mentat, how come you need a computer?  Mentats were
supposed to be the human replacements for computers after the Butlerian Jihad.
