-   This is writev, but with a constraint added and others loosened:
-
-   1. Under RTLD_PRIVATE_ERRNO, it must not clobber the private errno
-      when another thread holds the dl_load_lock.
-   2. It is not obliged to detect and report errors at all.
-   3. It's not really obliged to deliver a single atomic write
-      (though it may be preferable).  */
