AbstractTableViewer.virtualSetSelectionToWidget currently possibly iterates through all elements to get the index of a selection for VirtualTables.

The code contains the following comments:

// Now go through it again until all is done or we are no longer
// virtual
// This may create all items so it is not a good
// idea in general.

a "better" idea would be to at least check for IIndexableLazyContentProvider and call IIndexableLazyContentProvider.findElement(Object) instead if possible.
