I was thinking along the lines that going through a map will be shadowed by
file operations in the backend anyway, and thought it would be nicer to
group each decision with its config write. But I certainly wouldn't go and
test performance over it.

It was odd to me that the original code didn't check for the success of the
global config write, but I didn't want to touch it, lest I break
"transaction behavior" again :)

Then, fourth version attached.
