-## Testing Lock-Support
-
-The Lock support in Doctrine 2 is tested using Gearman, which allows to run concurrent tasks in parallel.
-Install Gearman with PHP as follows:
-
-1. Go to http://www.gearman.org and download the latest Gearman Server
-2. Compile it and then call ldconfig
-3. Start it up "gearmand -vvvv"
-4. Install pecl/gearman by calling "gearman-beta"
-
-You can then go into tests/ and start up two workers:
-
-    php Doctrine/Tests/ORM/Functional/Locking/LockAgentWorker.php
-
-Then run the locking test-suite:
-
-    phpunit --configuration <myconfig.xml> Doctrine/Tests/ORM/Functional/Locking/GearmanLockTest.php
-
-This can run considerable time, because it is using sleep() to test for the timing ranges of locks.
