Not to sidetrack the discussion, but this is one of the areas where
systemd does shine, in a sense.  If systemd thinks the service is
down, it is definitely down, because by default when systemd thinks a
service is down it kills anything it ever spawned (and it can
auto-restart if configured to do so).  So, this forces to you
configure the unit correctly so that you don't have these kinds of
maybe-running-maybe-not situations.

It is a bit like having strong types and stricter build-time error
checking.  It makes it a little harder to be lazier but saves you as
the user from the lazy developer.

As far as openrc goes, I suspect it is a pid file issue of some kind.
If a process goes and forks without putting the right pid in the file
then there is no way for openrc to detect this.
