title: Thread safety for DataTable
body: <p>I had read this answer <a href="https://stackoverflow.com/questions/2869101/ado-net-datatable-datarow-thread-safety">ADO.NET DataTable/DataRow Thread Safety</a>, and can't understand some things.
  Particularly I can't understand [2] article. What kind of wrapper I need to use?
  Can anyone give an example?</p>
  
  <p>Also I can't understand what author means talking about cascading lock and full lock. Please example too.</p>
