This really, really, really, bites. I think we need a guarantee that this never happens if ALLOW_MODESET is always used in blocking mode, plus in future a cap we can use to detect that we won't be getting spurious EBUSY events. I really don't want to ever paper over this, because it's one of the clearest indications that userspace has its timing/signalling wrong.
