It _is_, I've tried top explain in the paragraph below, just run the
test with large enough -i, sooner or late the test will run out of file
descriptiors and then it will fail.

The key here is that the run() function can be called repeatedly but
setup() and cleanup() are called only once at the start and at the end
of the test.
