It busy loops but it won't lock up as command completion is the loop breaker and command completion comes via IRQ and the busy looping doesn't happen solely in the IRQ context. Still needs to be fixed tho. Anyways, this is only limited to ->qc_defer for simplex and the reason why there's busy loop is because we're trying to schedule two independent hosts and SCSI midlayer (of course) doesn't have the notion of cross host deferring.
