--- Comment #1 from Frank Ch. Eigler <fche at redhat dot com> ---
For what it's worth, these caches are all disposable, so you could exclude the
whole directory structure from backups or just delete it.
I'm not keen on a file-attribute solution, because it's less portable and it'd
still require SOME file to exist. A 0-length file is not unambiguous (consider
empty source files). A differently named file is a possibility.
(Pretty sure atomicity is an orthogonal consideration - TOCTOU is a possibility
with all the options.)
