The patch assumes that pg_usleep won't change errno, an assumption I have little faith in.
Oh, right, at the very last loop. I've never seen it need more than 1 loop so I didn't manage to hit that codepath :) But yeah, saving errno and restoring it on the other side of pg_usleep is probably a good idea.
