  22  * Description:
  23  *   (1) step1: create a dynamic child in an onClipUnload handler of static_mc1;
  24  *   (2) step2: define a onUnload handler for the child;
  25  *   (3) step3: remove static_mc1;
  26  *
  27  * Observed:
  28  *  after step3:
  29  *  (1) onClipUnload for static_mc1 is triggered.
  30  *  (2) user defined onUnload for the dynamic child is NOT triggered.
  31  *  (3) the dynamic child is destroyed even without onUnload triggered.
  32  *
  33  *---case2---
  34  *  (1) step1: create a dynamic child in an onClipLoad handler of static_mc2;
  35  *  (2) step2: define a onUnload handler for the child;
  36  *  (3) step3: remove static_mc2;
  37  *
  38  * Observed:
  39  *  after step3:
  40  *  (1)onClipUnload for static_mc2 is triggered.
  41  *  (2)user defined onUnload for the dynamic child is triggered.
  42  *
  43  * TODO:
  44  *   seems createEmptyMovieClip() does not work in an user defined onUnload handler,
  45  *   not sure why, need more inspect later.
