+Note that, unlike `stream.push(chunk)`, `stream.unshift(chunk)` will not
+end the reading process by resetting the internal reading state of the
+stream. This can cause unexpected results if `unshift` is called during a
+read (i.e. from within a `_read` implementation on a custom stream). Following
+the call to `unshift` with an immediate `stream.push('')` will reset the
+reading state appropriately, however it is best to simply avoid calling
