/**
 * Annotation for asynchronous task mapping.
 * 
 * This annotation enables map step ({@link GridComputeTask#map(List, Object)}) for task
 * to be performed asynchronously when attached to {@link GridComputeTask} class being executed.
 * 
 * Use this annotation when tasks spawns large amount of jobs or map step takes a long time
 * and it is better to perform it in GridGain system thread.
