If a web server with PHP segfaults at 2 a.m. at a commerce web site, and
daemontools' 'supervise' restarts it in one second, and you are the admin
for the site. Your ass has just been saved. If you hadn't used supervision for
the server, the site loses thousands of dollars, or at least you get a call
in the middle of the night.

About syslog: funnel design. It's very inefficient. It's prone to crashes.
It eats a lot of CPU on busy boxes, then it complains that you're
logging too fast, and loses log records. It's garbage. That's why people
have written replacements.
