I would expect different SHRPOOLS to be cumulative, would probably bet big

less a dump. But what about multiple BLSR requests for the same SHRPOOL.
Does it sum them up and BLDVRP for the sum, just the largest, or what?

I question your logic with regard to BUFNI. If the access pattern is truely
dynamic, then the ideal would be to have space for the index sets and all
of the sequence sets, so that it never reads an index CI more than once. I
