title: Why does it take 100 seconds to delete a blob?
body: <p>I have code like this</p>
  <pre><code>BlobDownloadInfo blob = Client.GetBlockBlobClient(filePath).Download().Value;
  ...
  Client.GetBlockBlobClient(filePath).DeleteIfExists();
  </code></pre>
  <p>And DeleteIfExists() reliably takes 00:01:42 (about 100 seconds) to delete my blob. Why?</p>
