validateCells() behavior

Continuing the discussion from How do I make handsontable invalidate data for a pulldown?:

Sorry, took me a bit to get back to this problem. I tried your suggestion:

            hot.validateCells(function() {
                hot.render();
            });

But, when I do this (which is immediately after a loadData() command that adds a column, the column (about 100 rows worth) goes from being added instantly to taking about 15-20 seconds to render. During that time Chrome is using about 20% CPU. When I put a console log in there, I can see the callback is being called 444 times. Why would this cause that problem? How do I validate the loaded cells properly?
