    This is a Critical Section Controller; it will execute the set of statements (samplers/controllers, etc) under named lock.

    In a programming world - this is equivalent of : 

     try {
          named_lock.lock();
          statements ....
 } finally {
          named_lock.unlock();
 }
    In JMeter you may have : 
     Thread-Group (set to loop a number of times or indefinitely,
    ... Samplers ... (e.g. Counter )
    ... Other Controllers ....
    ... CriticalSectionController ( lock name like "foobar" )
       ... statements to perform when lock acquired
       ...
    ... Other Controllers /Samplers }
