 * ServerRepository::getAll keeps servers.php_pids out of the rows it returns
 * and of the 'servers' cache that every stream request reads. The column holds
 * one pid per live PHP-FPM worker of a node; only MAIN's cron:users needs it,
 * and it reads the column itself. (CacheCronJob's unset($rServers['php_pids'])
 * meant to strip it, but the map is keyed by server id, so it did nothing.)
