AIX does not, as I recall, have a daemon() call. That's one OS where you will have a learning experience. There are also a number of different ways to close open fd's. You probably don't care about special things for Domain/OS (it's been gone for a long time). Then there are things for setsid()/setpgid(), TIOCNOTTY, the no and 2 arg forms of setpgrp(), and SIGDANGER on AIX. There are probably other issues, too.
