includes/cache/MessageCache.php:281: $hash = $this->mMemc->get( wfMemcKey( 'messages', $code, 'hash' ) );

The long parameter is supposed to be language code. It is a bit tricky to know what to accept here without breaking uselang=xyz use cases. Length check seems okay to add, perhaps 35 chars which is the expected maximum for language codes.
