Say what? I thought the plan was one setting per file, so that we don't
get involved in having to parse-and-edit the file contents. What was
all that argument about a new directory, if we're only using one file?
If we are using just one file, then I agree a lock would be needed to
synchronize updates. But that seems to add a lot of complication
elsewhere.
