[Mondrian] Question on Aggregation

 We are currently looking on ways to optimize the usage of Synchronization 
block around aggregation load.
 Aggregation class has "constrainedColumnsBitKey" and "columns" fields. 
Our understanding is both of them represent the same columns list, in case 
constrainedColumnsBitKey and columns differ can someone give an example of 
when this could happen?

 We are wondering why "constrainedColumnsBitKey" initialized in 
constructor and "columns" initialized in load().
