title: Silverlight Event Log in Isolated Storage
body: <p>Has anyone written an event log that uses Isolated Storage in Silverlight 3?
  Any suggestions on implementing one?</p>
  
  <p>Specific questions:</p>
  
  <ol>
  <li>Should I keep a stream writer open, or should I open,write, and close for each entry?</li>
  <li>How should I remove items from the log atomically?</li>
  </ol>
