---------------------------------

Hi Gopal
Would you tell me what kind of information should be shown by /status ?

I found ReflectionUtils::printThreadInfo(), it looks to be used for this purpose.
Can I use this or should I make another function to get thread info?

> 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.
