This is something that has come up internally within Khronos. The correct
result (once the spec change lands) will be that basically all
vkQueueSubmit errors will actually result in VK_ERROR_DEVICE_LOST precisely
because of these sorts of issues. I've been meaning to send out a patch
that makes vkQueueSubmit turn all errors into DEVICE_LOST but haven't
gotten around to it yet.
