I understand what is at stake, my problem is that in other *Unixes, sysV/Solaris
'shutdown now' is actually sometime in the future :-), and it does not help
much if you are far away and the link is slow, so the 5 sec. grace is actually
taken up by the bandwidth - or you are connected via an iphone, how do you
hit ^C :-)

what if the machine is compromised and you really want to power it off,
now the intruder has another 5 seconds ...

thankfully +0 works, or are there plans to change that too? :-)

careful! bikeshead ahead
