Whether to use the system threadpool to obtain information on listview items.
Setting this property to true currently has issues on Vista and Windows Server 2008, therefore the default value is false.
If this property is false, the complete file detail information is retrieved as
soon as the item is displayed the first time within the listview.
Sometimes it is useful to have all file information fetched as soon as possible without loosing userinterface
responsiveness. If set to true, the item information for all files in the listview is additionally
fetched from the background this further enhances performance on multicore systems.
The setting of this property affects the control the next time the FullRefresh()()() method is called.
