/*
 *---case1---
 *
 * Description:
 *   (1) step1: create a dynamic child in an onClipUnload handler of static_mc1;
 *   (2) step2: define a onUnload handler for the child;
 *   (3) step3: remove static_mc1;
 *
 * Observed:
 *  after step3:
 *  (1) onClipUnload for static_mc1 is triggered.
 *  (2) user defined onUnload for the dynamic child is NOT triggered.
 *  (3) the dynamic child is destroyed even without onUnload triggered.
 *
 *---case2---
 *  (1) step1: create a dynamic child in an onClipLoad handler of static_mc2;
 *  (2) step2: define a onUnload handler for the child;
 *  (3) step3: remove static_mc2;
 *
 * Observed:
 *  after step3:
 *  (1)onClipUnload for static_mc2 is triggered.
 *  (2)user defined onUnload for the dynamic child is triggered.
 *
 * TODO:
 *   seems createEmptyMovieClip() does not work in an user defined onUnload handler,
 *   not sure why, need more inspect later.
