>
> To prevent thread-conflicts in executor information, the Apache HTTP servers
> use a share-nothing data structure known as a scoreboard.
> This is read by various systems like mod_status to read out the current state
> of executors available for PHP (and similar mod_* engines).
> The /status output is traditionally periodically read by the load-balancers
> to route requests away from busy machines.
