Class which provides the isolation semantics required by an IsolatedWork. Processing comes in two flavors:

doIsolatedWork : makes sure the work to be done is performed in a seperate, distinct transaction
doNonTransactedWork : makes sure the work to be done is performed outside the scope of any transaction
