      Description

      AbstractTask's IsolatedActionJournal and ReadOnlyJournal classes allocate a TemporaryStoreFactory for each task instance. This could create a very high overhead for full transactions. At stake is whether the temporary store accessible to the task is "isolated", which includes visibility and/or concurrency concerns. The comments in the code suggest that a better solution would be to introduce the concept of isolation into the resource locator mechanism.
