Looks good!

We should probably think about changing the Zope storage config sections
on the chrism-install-branch to match those spelled here.  I imagine we
can play around with Fred's schema import stuff a bit to try to do that.

I think we also need to include event log configuration data (we should
stamp out usage of ennvars like EVENT_LOG_FILE and STUPID_LOG_FILE when
possible and allow folks to write ZEO log messages to other kinds of
handlers).

I wonder if we can get rid of the funkiess of trying to use CLIENT_HOME
and INSTANCE_HOME in ClientCache.py as well by relying solely on the
"var" directory set via a zeoclient storage config section.

I haven't tried the zdctl stuff so I'm not sure how all that ties in at
the moment.

Thanks!
