Description
http://jsfiddle.net/godric/ZjTzy/
Simple, using multiple-selector to fetch 400 elements on IE7, but fine on firefox, chrome, safari.
jquery-1.4.2 = medium 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?

Some more cross-referencing:
I guess it's the same bug as #7341, the multiple-selector might be using .add() internally.

Replying to godric: We are also stuck with 1.4.2 because of this checkSibling() IE problem. We have a page with 1.4.3+, UI 1.8.11, and a dialog with a large multiple select (hundreds of options). If you click on an option, IE 7/8 freezes in endless JS calls to checkSibling(). Please re-open 7341, many users will be stuck with 1.4.2 until it is fixed.

I can concur that the fix in http://forum.jquery.com/topic/is-this-a-regression-or-a-known-issue-in-1-4-3-and-ie7-8 works

I think this bug can be closed too. I had lots of problems while selecting lots of elements with jQuery > 1.4.2, but using 1.6.1 (and 1.6.2) solves the issue.
In fact, I think it's faster now...
