Well, It works now.  I changed the loop that fills the list.  It used to
look like this:

while (my $ref = $sth->fetch) {
        no warnings;
        $list->append(@$ref);
        use warnings;
}

Now it looks like this

while (my $ref = $sth->fetch) {
        $list->freeze;
        no warnings;
        $list->append(@$ref);
        use warnings;
        $list->thaw;
        Gtk->main_iteration while (Gtk->events_pending);
}

The freeze and thaw don't help, but letting the Gtk main loop process
stuff while I am loading the loop has two great features:  one
columns_autosize now works and two my application no longer freezes when
I run an sql command (And I wasted all that time trying to get
multi-threading to work, sigh).
