I'm working on a replacement for daemon(3) as a way of fixing PR
48282, and this seemed like a good way to give the code a workout
before giving it wider exposure in a place like libc.

This particular daemon is simple enough that it probably could have
used daemon(3) without problems, but I'm aiming for a general solution
that will work even for daemons that use threads or kqueues.  Those
cause problems with daemon(3) because they aren't inherited across a
fork, which forces you to daemonize early, which in turn leads to race
conditions as the parent process continues before the daemon is ready
to provide service.
