	Well, the flip side of that performance coin is that once you
load the DataTable, you can cache it in memory and use it as many times
as you like without hitting the database again at all!

I think the solution here is to load all of the rows into a DataSet
of trying to load 15 rows at a time into a DataReader.  I was hoping to 
avoid that with a slick query, but I'm not making it work, so....
