One more thing, this needs runtime treatement since if you pass large
enough file size the test will timeout.

First of all we should add large enough max runtime as we do for the
rest of the aio tests, i.e. .max_runtime = 1800,

And secondly, I would do that in a subsequent patchset, we should add
check for running out of runtime into the worker loop.
