A windows form; error condition in issue is activated with buttons on the form.

If the width of the header within a list view is set to too large a value, the
list view will flicker and try to use all of CPU.  

In the attached test project, this column width is set with this line:

listView.Columns[0].Width = this.Width + 1000;

Windows is able to handle this situation without screen artifacts or excessive
CPU use.
