I miss at RP a method similar to
Thread.currentThread(). Namely:

/**
 * @return RP.Task hosting code that invoked this
 * method or <codE>null</codE> if it is not called
 * from RP.Task body.
 */
public static RequestProcessor.Task currentTask();

Even further I'd appreciate RequestProcessor.Task
enhancement:

/**
 * @return true if it was canceled after dispatching
 */
public boolean canceled();


or RequestProcessor enhancement:

/**
 * @return true if currently executing RP.Task
 * was canceled after dispatching. I.e. always false
 * for non RP threads.
 */
public static boolean canceled();
