It is, something submitted with RWF_NOWAIT should have IOCB_NOWAIT set.
But RWF_NOWAIT isn't the sole user of IOCB_NOWAIT, and no assumptions
should be made about whether something is sync or async based on whether
or not RWF_NOWAIT is set. Those aren't related other than _some_ proper
async IO will have IOCB_NOWAIT set, and others will not.
