I'm a firm believer in the latter approach, so that code which starts a
daemon can wait for it to be usable by waiting for the pid to exist.

Now, there's an argument that perhaps the parent process should not exit
until the pidfile exists, and should propagate SIGINT ... there might be
arguments, but such a feature request, perhaps tied to a new
command-line flag, seems reasonable to me.
