At least one such a test case exists for the file mappings, and actually
making it pass has motivated me for this kind of patches. It shows that
a mapping created with access 0 is not accessible. Since all the objects
on the server side share a single access check mechanism it's impossible
to make one test pass without either changing that single mechanism, or
creating separate access checks for every type of an object.
