+ * from any thread.

+ * The main purpose of this method is to indicate that you believe a method can be called
+ * from any thread; static tools can then check that nothing you call from within this method
+ * or class have more strict threading requirements.

+ * <pre><code>

+ *  public void deliverResult(D data) { ... }
