title: Kill Eclipse background operation without killing Eclipse
body: <p>Is there any way to kill an Eclipse background operation without killing Eclipse itself? </p>
  
  <p>Specifically, I want to kill stalled Subclipse SVN operations.  Clicking 'cancel' pops up a little <em>Cancel Requested</em> message, but the operation still sits there forever blocking everything else.</p>
  
  <p>This is Eclipse Helios on Windows 7 if that makes any difference.</p>
