> When a CAS is delta-serialized, the journal is processed to convert it to a 
> set of adds, removes, and reindexes.  This process needs add, remove and find 
> operations on sets of ints.  It is using the IntSet implementation, which 
> underneath uses the IntVector data structure - which is very fast for add, 
> but order (size) for contains / removes, etc.  Change this to the 
> PositiveIntSet (requires adding toIntArray method to PositiveIntSet), which 
> has order 1 contains/remove operations.
