Out of curiosity I have a mysql_db play in a playbook that imports a database into a pre-production environment. I added single_transaction=yes to it and the import never fully finished. Not sure if this is a bug or some external issue but since this is new functionality I’d be willing to aid in testing it.
Care to share your playbook? And the exact error messages?

I had that sometimes, then I killed the process on the target host,
and voilá I had some error message on the controller running the
ansible task (I run with -v, to get more output).
I would guess it waits for input. Forever.
