// (the problem case) to deal with its event queue. This is
// necessary when holding down a key such as 'page down' or
// just typing: without this processing of the event queue,
// the cursor gets ahead of itself without a selection or
// workarea redraw having a chance to keep up. If you think
// you can remove this, try selecting text with the mouse
// in Qt, or holding Page Down on the User's Guide.
