Indeed, the delete-upon-load is also a heuristic and it's not necessarily
better than any other. I think anything is OK, as long as it's run at least
once per Emacs session where you use thumbs without being run too often to
slow everything down.

executable-find is not expected to modify any state: it doesn't
create/modify/delete any file for exemple. It's more or less
a "pure" function. Some files even run programs upon load (typically
things like "ispell --version"), and while it's often sub-optimal, it's
still OK as long as the program itself won't change any state either.

toto_NNNN.jpg would be the thumb for (e.g.) baz/toto.gif.
The NNNN is in case you want to add a hash or counter.
