That really isn't true. This isn't done just once. It's done many thousands of times. I agree that it has to be robust, but if we want to make suspend/resume be instantaneous (and we do), performance does actually matter. Yes, this is probably much less of a problem than waiting for devices, and no, I haven't timed it, but if I counted right, we'll literally be going almost ten thousand of these calls over a suspend/resume cycle. That's not "rarely used".
