I'd have thought it's better to continue using speedycgi and kick
speedycgi when you change the config.  That way you won't cause so
many discontinuities in the data.  After all, that's just the sort
of thing you'll be looking for and you don't want them to be hidden
amongst the things you caused yourself.

Much better to send a SIGUSR1 to Apache, so it acts gracefully:


I don't use nagios, so I can't tell you much about it, but apparently
it has the 'reload' command, or you can send it SIGHUP:


I'm a Sendmail fan, but they tell me Postfix has the 'reload' command:


Yes, BIND is a little different.  It has 'rndc' which can take the
'reload' option:


But I'm straying way OT now.
