title: Why does npm flash "verb" and "sill" while installing things?
body: <p>I'd like to understand what is intended to be communicated by the words "verb" and "sill" when installing node modules via npm:</p>
  
  <pre><code>⋊&gt; ~/t/quill on develop ◦ npm install                                                                                                                                  15:35:02
  ⸨      ░░░░░░░░░░░░⸩ ⠙ fetchMetadata: sill mapToRegistry uri https://registry.npmjs.org/big.js
  </code></pre>
  
  <p>The <code>sill</code> right before <code>mapToRegistry</code> also changes to <code>verb</code> and back again. What do these mean?</p>
