> If multiple locks are associated with a TransactionEntry, it's highly non-performant, since for each addition the class does a contains() check on a LinkedList.  We should replace the LinkedList fields with LinkedHashSet.  With that, the contains test can be removed all together, as a 2nd add of the same object to a LinkedHashSet has no impact on the collection ordering.
> See forum post for profiling info on the current impl.
