I get a little fuzzy on when the changeover from user root to user zope
happens, but this is the confusing point, and why I originally excerpted
the directory listing: doesn't (effective) user zope already have
read-write on the Data.fs.lock file?

Should I add user root to group zope, or would that defeat the security
purpose of the effective-user? Or can you recommend the correct chmod
setting for this setup, I don't want to 755 the thing into wide-open
access without knowing what I'm doing. Thanks.
