// Simple, using multiple-selector to fetch 400 elements on IE7 will hang,
// but it's fine on firefox, chrome, safari.
// jquery-1.4.2 = slow but it will finish.
// jquery-1.4.3 = won't finish, need to stop script manually.
// Suspected to be related to the new browser-native-optimizations.
// 1.4.3 performs far worse than 1.4.2 on IE7, abnormally & unbearably worse,
// maybe some unsuitable optimization got turned on by mistake on IE7?
// *** (2011-05-16) WHEW!! FINALLY!! ***/
// the .add()/sourceIndex fiesta is FIXED @ 1.6.1 !!!
// Also as mentioned in http://bugs.jquery.com/ticket/7341,
// 1.6.1's IE-.add() is ~10% slower than 1.4.2's, aligned with my feel of it.
// But heck, at least it doesn't hang... Thanks!!!
