Because in this case we don't control when real async ioctl is called,
as far as I understand we may hit it earlier and hide real case of
problem.

After all your questions, I started doubting if the changelog is correct.
For sure the reason of failure is async ioctl call over terminal
which is not alive (since with the patch container passes this point
of restore) but maybe I've overlooked something. Gimme some time...
