If we go back to the recent fixes OpenBSD did first, the cvs logs give
reasons like,
daemon() can close innocent file descriptors, including opened log.
be more carefull about that and nicer to debugging.
daemon() thingie was pointed out by markus@ .
So it's not really a security issue that I can see. I'm not sure if I
understand under what conditions a daemon(3) call will close
"innocent" file descriptors.
