The current ExecReload code apparently intentionally doesn't allow for a
restart-like operation, though.  If ExecReload replaces the process with a
fresh PID, that PID ends up getting SIGKILL'd by systemd.  cf. this

 I've confirmed similar behavior recently with my daemon and F18's copy of
systemd.
