+In most cases, this is identical to a simple `stream.destroy()` call. The rules
+are as follows for a given stream:
 
   1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
      and add a listener to the `open` event to call `stream.close()` if it is
      fired. This is for a Node.js bug that will leak a file descriptor if
      `.destroy()` is called before `open`.
-  2. If the `stream` is not an instance of `Stream`, then nothing happens.
-  3. If the `stream` has a `.destroy()` method, then call it.
+  2. If the `stream` is an instance of a zlib stream, then call `stream.destroy()`
+     and close the underlying zlib handle if open, otherwise call `stream.close()`.
+     This is for consistency across Node.js versions and a Node.js bug that will
+     leak a native zlib handle.
+  3. If the `stream` is not an instance of `Stream`, then nothing happens.
+  4. If the `stream` has a `.destroy()` method, then call it.
 
 The function returns the `stream` passed in as the argument.
