The load() function already returns just one entity or NULL, so the current() is not needed and the result can be returned directly.

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:
- Go to http://www.gearman.org and download the latest Gearman Server
- Compile it and then call ldconfig
- Start it up "gearmand -vvvv"
- 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.
