With both of these flags, the backup was created via rename(dest, backup) followed by rename(tmp, dest). This left the destination file missing for a moment which contradicts the point of -S. This fixes a race with installworld where PRECIOUSPROG and PRECIOUSLIB files (which use -S for installation) would briefly be missing. In the case of installing rtld with parallel installworld it could render an error due to not having rtld present to run install/cp in another process.
