[IDV #NTD-472266]: Excessive loading of data in bundles

Jim,
        I thought you were modifying your old bundles. But, I believe I know 
what went wrong now.
The problem is that the IDV don't have the subset information when calling 
these diagnostic function. Those
subset information including the time matching, are hiding in its parameters 
and the parameters can be derived
itself. So, some of the logic must be wrong in the current release. I will find 
a solution asap.
