various data structures and objects. A reading thread that's executing this
method could be reading while the balancing thread is writing to these data
structures and objects. This is code is not thread safe and can cause
unpredictable errors. Some other thread safety issues could be there in this
class and ContainerBalancer as well. (was: The method
