title: DotTrace.SaveData hangs execution
body: <p>I am using the JetBrains Self Profiling API.  For the most part it works great, but I have hit a problem that sometimes when I call <code>DotTrace.SaveData</code> it does not return.  <code>DotTrace.SaveData</code> just keeps executing and thus everything after it does not get executed.</p>
  <p>What I have tried:</p>
  <ul>
  <li>Put it in a <code>try</code> <code>catch</code> block.</li>
  <li>Ensure that the target folder is not locked.  (It can write the intermediate files just fine.)</li>
  <li>Ensure that there are not other instances or threads calling <code>DotTrace</code> profiling methods.</li>
  <li>Ensure that the profiler has been initialized and attached.</li>
  </ul>
  <p>It is frustrating because it does not throw an exception or give any details.  It just hangs.</p>
  <p><strong>How can I debug more what is causing this issue?</strong></p>
