Executing a WorkUnit

The ThreadWorker can expect that its executeWorkUnit method will be called once for each ThreadWorkUnit that the ThreadWorker will process. For example, if the batch process will act upon 10,000 accounts, and the process is submitted with a ThreadCount=10, we can expect that there are 10 ThreadWorkers created by the framework, each of which will have its executeWorkUnit method called by the framework for each of the 1,000 ThreadWorkUnits allocated to that thread.
