title: Is it possible to kill the BackgroundWorker's thread?
body: <p>Is it possible "kill" the thread of a <code>BackgroundWorker</code>?</p>
  
  <p>In my <code>DoWork</code> event, I can't check the cancellation flag, because I have a blocking 
  call to an external COM interface or a query to a database. <code>CancelAsync</code> doesn't cancel the call to COM.</p>
  
  <p>How can I do it, please ? Any suggestions will be very appreciated.</p>
  
  <p>Thanks in advance.</p>
