* This will be heavily inspired by Apple's launchd, as well as
systemd -- for now it really doesn't do a whole lot, though.
* What works so far: the configuration files are read, parsed, and
the jobs created.
* The jobs are even initialized, and their message ports created.
* BApplication now retrieves a previously created port from the
launch_daemon for use with BServer.
* Only the registrar actually uses this for now.
