+ *   <li>Forces exceptions to crash the application, unless the user implements their own onFailure

+ *   <li>Checks for dead UI components which can be encountered if a UI task runs longer than its
+ *       UI. If a dead UI component is encountered, onSuccess/onFailure are not called (because they
+ *       can't be) but a message is logged.
+ *   <li>Helps prevent memory leaks in UI tasks by ensuring that callbacks are nulled out when the
+ *       headless fragment is detached.
+ *   <li>UI and non-UI threads are shared across the application and run at reasonable priorities
+ * </ul>
+ *
+ * <p>Executors accept a single input and output parameter which should be immutable data objects.
+ * If you don't require an input or output, use Void and null as needed.
+ *
+ * <p>You may optionally specify onSuccess and onFailure listeners; the default behavior on success
+ * is a no-op and the default behavior on failure is to crash the application.
+ *
+ * <p>To use an executor from a UI component, you must create it in your onCreate method and then
+ * use it from anywhere:
+ *
+ * <pre><code>
+ *
+ * public class MyActivity extends Activity {

+ *
+ *   private void userDidSomething() { myExecutor.executeParallel(input); }
+ * }
+ * </code></pre>
+ *
+ * <p>Usage for non-UI tasks is the same, except that tasks can be created from anywhere instead of
+ * in onCreate. Non-UI tasks use low-priority threads separate from the UI task threads so as not to
+ * compete with more critical UI tasks.
+ *
+ * <pre><code>
+ *
+ * public class MyManager {
