They already had it, they just need to learn how to take advantage of
the environment they're working in.

Thats good.

Its desirable in some circumstances, but not all.  Part of the problem
is people tend to blindly follow the traditional approach to daemon
design without bothering to actually do any critical thinking.  There
are several very reasonable arguments for deviation from the
historical approach.  Perhaps the most relevant argument is the same
old one about the Unix design philosophy; many small programs working
together is more a flexible and ultimately useful approach than a monolithic
one-program-does-it-all design.

Anyway, if you want to question authority, consider reading:
http://homepages.tesco.net/~J.deBoynePollard/FGA/unix-daemon-design-mistakes-to-avoid.html
or http://cloud9.hedgee.com./scribbles/daemon or even better yet, look
back over the CVS commits and bugs fixed in the Zope code (or other
traditional-design daemons) that have been related to the current
design choices and think about how they could have arisen under the
more modular approach and how they might have been fixed in those
circumstances.
