I am putting up a listbox that shows a list of 
groups. In a second column I show how many 
records belong in each group -- that can take 
some time to calculate, so I want to put up the 
list first and fill out the # of items per group 
in a thread. Kind of like in the Finder where 
folder sizes can be updated gradually in the list 
view. The calculations in the thread require 
Valentina queries. What we're seeing with big 
databases and lots of groups is that the UI 
freezes. We're also getting a locked table error 
(but I think I can work around that -- it's the 
UI that's the problem).
