From manual page: http://www.php.net/gearmanworker.addserver
---

GearmanWorker::addServer will establish a TCP connection with gearmand server. This is not the same behaviour as documentation says.

run test script and try the following from your gearmand server:

lsof -i tcp | grep gearman

you can notice that a TCP connection is already established even if we do not call $gearman_worker->work() 

Test script:
---------------
<?php
$gearman_worker = new GearmanWorker();
$gearman_worker->addServer('localhost', 4730);
sleep(100);


Expected result:
----------------
no connection is established when addServer is called alone

Actual result:
--------------
a TCP connection is observed when addServer is called alone
