title: What do the columns in the Object Alloc instrument mean?
body: <p>I was unable to find the documentation for this. There is no Quick Info.</p>
  
  <p>The columns have these opaque titles:</p>
  
  <pre><code>Category
  
  Live Bytes
  
  # Living
  
  # Transitory
  
  Overall Bytes
  
  # Overall
  
  # Allocations (Net / Overall)
  </code></pre>
  
  <hr>
  
  <p>Is there a document that shows what these columns mean? Without having to read 600 pages?</p>
