/*
 * Test "Jumping backward to the start of a DisplayObject's lifetime after being swapped to the depth of a subsequently placed DisplayObject"
 *
 * Timeline:
 * 
 *   Frame  | 1 | 2 | 3 | 4 | 
 *  --------+---+---+---+---+
 *   Event  |   |P* |PM | J |
 * 
 *  P = place (by PlaceObject2)
 *  M = move to another depth (by swapDepth)
 *  J = jump
 *  * = jump target
 *
 * Description:
 *
 *  frame2: a static DisplayObjects is placed at depth 2 (-16381) [ a red square ]
 *  frame3: a static DisplayObject is placed at depth 3 (-16380) [ a black square ]
 *          the two DisplayObjects are depth-swapped
 *  frame4: jump to frame 2 and stop.
 *
 * Expected behaviour:
 *
 *  A single instance of each DisplayObjects is created.
 *  After loop-back only the DisplayObject placed in frame 3 is still alive (the black square),
 *  at depth -16381. The DisplayObject placed in frame 2 has been destroyed !
 *
 * run as ./loop_test3
