But is it OK to resubmit straight away (I don't know anything about iso)?

-EAGAIN         a) specified ISO start frame too early
                b) (using ISO-ASAP) too much scheduled for the future
                   wait some time and try again.

It sounds like maybe there should be a delay before resubmitting.
Couldn't you get into a pretty tight loop?
