Firstly, I've *never* had problems with refresh (as a user of) until
Zope 2.7 (I only use it on my own products, so I must naturally code
in a refresh friendly manner). I'm used to developing with autorefresh
switched on for my products and it just *works*. If I make a change and
don't see the expected behavior, I switch to the product refresh page to
see where the syntax error is that caused the refresh to fail.

I've occasionally also used manual refresh to reload products on
production servers without nuking sessions, but apart from that it is
startup/teardown time. This is a problem though because doc/INSTALL.txt
tells us to:
	./configure
	make instance

Until following the steps in doc/INSTALL.txt fires up a single ZEO
server bound to the loopback address and a single ZEO client (with
authentication on), the vast majority of developer and production
installations will be ZEO-less. This also makes ZEO-less installations
the best tested and most stable environment, or at least people will
assume so.
