One could of course discuss how long a scripts should be allowed to
maximum delay the shut down. In that discussed case, it's at maximum
60 seconds now if a fax is just being send, but one could ask for
longer to be able to finish more than half a page. (And, it wouldn't
be any problem for _that_ case here if the daemon would just be killed
with -INT if he takes too long in opinion of the shutdown-script, as
this would mean: shutdown NOW, and abort any faxing just in operation.)
So, some maximum time (or even a "force-stop"-target, or a
"background-stop"-target) should be discussed, because all arguments
are true in their specific setup.

In the case of inn, it's very clear that it _needs_ the whole time. In
the case of mgetty-fax, it's just a question whether fast shutdown is
more important than to avoid to send out a fax twice (and waste money
with that).
