  "Under SVR4, some people recommend calling fork again at this point and having the parent terminate. The second child continues as the daemon. This guarantees that the daemon is not a session leader, which prevents it from acquiring a controlling terminal under the SVR4 rules. [...]" (That's from p417 in my first edition copy of Stevens. The page number and/or the text may be different in the second edition.)
